Sharon Kleinbaum, rabbi of influential LGBTQ+ synagogue Beit Simchat Torah, is stepping down
(New York Jewish Week) — Sharon Kleinbaum, the first full-time rabbi of Manhattan’s Congregation Beit Simchat Torah, announced that she is stepping down after three decades leading New York’s influential LGBTQ+ synagogue.
In an announcement to congregants, Kleinbaum, 63, said that “this is the right time to make room for a new senior rabbi for CBST.”
“CBST is in a strong place for the next chapter, and I am confident in our future,” she wrote. “CBST is a place of deep spirituality and a center of activism rooted in Jewish values, texts and justice. It will be spiritually meaningful for CBST to discover who it is without me as the senior rabbi and for me to discover who I am apart from CBST.”
Kleinbaum, who plans to leave her post next summer, wrote that her official departure is “many months” away.
A New Jersey native, Kleinbaum was ordained at the Reconstructionist Rabbinical College and came to the unaffiliated CBST in 1992. The synagogue, incorporated in 1973, had been meeting in Greenwich Village, and decided to hire a full-time rabbi at what was the height of the AIDS crisis and when the need for pastoral care was urgent. Soon after, more than 2,000 people attended CBST’s Yom Kippur services at the Jacob Javits Convention Center, at the time the largest-ever gathering of lesbian and gay Jews. That number has since grown to over 3,000 people annually.
In 2016, CBST moved into a new home on the ground floor of 130 West 30th Street, an 18-story building between 6th and 7th Avenues.
During her tenure, Kleinbaum has steered the synagogue’s activism in LGBTQ+ issues and beyond. In 1995, she and other activists successfully pushed for a resolution seeking support for civil marriage for gay couples that was approved by the Reform movement’s Central Conference of American Rabbis in 1996. She regularly weighs in on municipal issues, including immigration, paid sick leave for workers and policing policies.
At the same time, CBST expanded its children’s programming, with a Hebrew school, children’s services and educational programming.
Kleinbaum is a supporter of the liberal pro-Israel lobby J Street; in 2020 a right-wing political action denounced her in an ad calling her an “antisemite,” drawing condemnation from the Anti-Defamation League and others.
Kleinbaum, who regularly makes lists of the country’s top rabbis and religious leaders, was also a co-founder, in 2020, of New York Jewish Agenda, a progressive advocacy group.
NYJA “arose from a sense that there is a Jewish voice that exists widely throughout New York, but that is uncoordinated,” she said at the time. “The mainstream liberal Jewish voice is not getting out into the public square in the way that it should.”
In 2021, she was named by President Joe Biden to the U.S. Commission on International Religious Freedom.
In 2018 she married Randi Weingarten, president of the American Federation of Teachers. The rabbi and the union leader appear to enjoy their role as a progressive power couple: After former Trump administration official Mike Pompeo called Weingarten “the most dangerous person in the world” in November, Kleinbaum was photographed in a T-shirt reading, “I am proud to be married to the most dangerous person in the world.”

Antisemitic AI Videos Target Children With Disney-Pixar Style to Push Holocaust Denial, Report Shows
AI-generated videos found on TikTok, Meta, YouTube, and X imitated popular animation styles from Disney-Pixar movies to present Holocaust denial and antisemitic tropes to children.

A pathbreaking report released this week reveals that online users have started exploiting AI video generators to weaponize the nostalgia of Disney-Pixar styles, wrapping venomous hate in a candy-coated shell to reach youth.
On Sunday, CyberWell, a Tel Aviv-based nonprofit focused on monitoring antisemitism on social media, published research tracking 307 identified pieces of AI-generated content targeting Jews on social media between January 2025 and February 2026. The group found that the images and videos received 30 million views and more than 2.8 million user interactions such as likes or reshares. They observed animations created with OpenAI’s Sora, Google’s Veo, X’s Grok, and Suno.
While TikTok accounted for the biggest chunk of the content at almost 36 percent, the popular video-sharing service also came through with the highest level of enforcement at more than 88 percent. Instagram drove the top rates of engagement, accounting for almost 65 percent while its total antisemitic posts reached nearly 25 percent.
The Meta platform saw a removal rate of 67 percent, notably higher than Alphabet’s YouTube (28 percent) and billionaire Elon Musk’s X platform (20 percent). Musk recently incorporated X, xAI, and its Grok chatbot into his rocket company SpaceX before an anticipated IPO in June.
CyberWell found three primary narratives across the videos: 33.2 percent portrayed Jews as greedy or money-obsessed, 21.5 percent involved the Holocaust, and 21.2 percent presented violent rhetoric against Jews inspired by a specific event, in this case the June 2025 Israel-Iran conflict and the viral video “Boom, Boom, Tel Aviv.” The video features such lyrics as “Boom, boom, Tel Aviv. This is what you get for all your evil deeds […] You brought this upon yourself, it’s your time to bleed […] Humanity never expected good behavior from you Jews.”
The researchers called mid-2025 a turning point in the rise of AI-driven antisemitic videos, with 98.4 percent of identified content originating from that point forward.
The report describes “a recurring pattern in which users package AI-generated antisemitic content in formats designed to appeal to younger audiences. The most common examples include fabricated Disney-Pixar-style movie trailers and gaming-related audio clips that promote Holocaust-related mockery, antisemitic conspiracy theories, and hate speech targeting Jews.”
One of the techniques users attempt to evade moderation is to label such videos with tags claiming “satire” and “dark humor.” Others will use the term “Caust” instead of “Holocaust.”
One example presented features a fabricated trailer for a “Caust” movie created with Sora in the Pixar style. Researchers described how “set in a concentration camp, the trailer portrays Adolf Hitler in a lighthearted manner while following a group of Jewish child prisoners attempting a dramatic escape. By presenting the Holocaust in a playful, animated format, the video turns atrocity into entertainment and diminishes the gravity of Jewish suffering.”
The AI videos also exploit kids’ love for video games.
One TikTok video created with Sora and titled “CAUST COMMANDER” received 66,500 views, 4,623 likes, and 3,619 reposts. According to the report, “the post portrays Adolf Hitler in a playful, stylized manner while depicting him killing those around him. The video makes light of the Holocaust and the mechanisms used to exterminate Jews by presenting them in a gamified, commercialized format, including the promotion of fake merchandise such as Zyklon B gas, themed outfits, and ‘back bling.’”
On March 24, OpenAI announced the decision to shut down Sora following months of reporting on antisemitic content proliferating across the platform. Analysts judged that the decision was reportedly motivated by a need to free up computational power for the training of new models so OpenAI could remain competitive as Anthropic’s Claude surges in popularity among coders and Alphabet’s Gemini draws away users.
The report emphasizes the deep extent to which antisemitism has penetrated AI systems.
“Many of the websites used in AI training datasets function as active hubs for antisemitic discourse, raising concerns about their inclusion in model development,” the report says. “For example, Reddit ranks among the most cited domains across major AI systems, while analyses of ChatGPT outputs indicate that Wikipedia alone contributes to roughly half of generated responses. The reliance of AI companies on these websites underscores the risk that antisemitic narratives circulating online may become embedded in model inputs and later disseminated at scale.”
CyberWell CEO and founder Tal-Or Cohen Montemayor warned that AI had turbo-charged both the speed and intensity of online antisemitism.
“Artificial intelligence has fundamentally changed the scale and speed at which antisemitism can be produced and distributed online,” Cohen Montemayor said. “Generative AI now allows bad actors to industrialize hate, producing high-impact content that can reach millions, with enforcement often coming only after it has already been widely amplified.”
Cohen Montemayor added that CyberWell’s latest report “examining the circulation of antisemitic AI-generated content on major platforms provides critical insights for how social media platforms can take on the abuse of generative AI tools to spread antisemitism in the digital universe.”
CyberWell found that while the Pixar-fied, disarming aesthetics targeted children, it was the videos openly glorifying violence that provoked the highest level of shares reaching 33 percent of content but 41 percent of engagement.
Cohen Montemayor called for the platforms to “move beyond disclosure and invest in systems that identify harmful narratives at scale, including those embedded in audio, visuals and coded formats that evade traditional detection.”
Warning that AI was “being weaponized at scale,” Cohen Montemayor explained that “by strengthening automated detection, investing in competent and transparent human moderation, auditing training data and partnering with specialized external stakeholders, platforms and AI developers can address the complex and fast-evolving forms of online hate through sustained collaboration between technology companies, policymakers and expert partners.”
In one of the most closely watched legal battles in artificial intelligence, a jury on Monday ruled against Musk in a lawsuit the billionaire filed to force OpenAI to revert fully to its original nonprofit mission. Jurors decided that Musk had filed his suit too late.
The world’s wealthiest man faces potentially more severe legal challenges in response to his AI business in France, where prosecutors said they intended to pursue criminal charges due to the Grok chatbot’s promotion of Holocaust denial and generation of child sexual abuse images.

Yeshiva University Holds Conference Calling for ‘Social Science’ Study of Rising Antisemitism

Vital new data, scholarship, and moral encouragement were exchanged during a national conference Yeshiva University held earlier this month to promote the study of antisemitism as a “social science problem,” several academics who attended the event told The Algemeiner in exclusive interviews.
The “Antisemitism Conference” brought some 200 academics to the institution’s campus in Manhattan, New York amid a moment many Jewish community advocates have described as a “crisis” of antisemitism. Across the US, Jews have faced discrimination, battery, and even death over their Jewish identity and for being Zionists. Having seen the situation plunge to unprecedented lows, Yeshiva University called on scholars from a range of fields to use their expertise to explore and report on the matter.
Following the conference, Raeefa Shams of the Academic Engagement Network (AEN) told The Algemeiner that the academic community was responsive and arrived at the event with a harvest of findings and insight.
“They presented research they are in the process of conducting or in the process of publishing,” Shams said. “For example, we had one faculty member who presented on the correlation between anti-Israel attitudes and conspiratorial, antisemitic thinking. There was another scholar who presented on the experience of Jewish students with antisemitism post-Oct. 7. We had somebody else present about antisemitism within the American Psychological Association. We had a clinical psychologist talk about antisemitism and traumatic invalidation.”
The Algemeiner has covered a wide range of antisemitic incidents which transpired on the streets and campuses of the US since Hamas’s Oct. 7, 2023, attack on Israel unleashed a spike in global antisemitism. These included, among many other examples, a public-school principal inveighing against “Jew money,” an attempted arson at the Hillel International chapter in San Francisco, California, and the movement of some conservative students into the far-right ecosystem of antisemitism. In New York City, home to the world’s largest Jewish population outside of Israel, Jews have been targeted in the majority of all hate crimes this year despite comprising a small fraction of the total population.
The wave of hatred has changed how American Jews perceive their status in the US. According to the results of a previous survey commissioned by the Anti-Defamation League (ADL) and the Jewish Federations of North America, a striking 57 percent of American Jews believe “that antisemitism is now a normal Jewish experience.”
Higher education can lead the way in reversing this trend if it promotes the adoption of “trauma informed” policies, clinical psychologist Dr. Mari Bal-Halpern, told The Algemeiner.
“There needs to be a safe environment. That does not mean that we’re silencing voices, but it needs to be safe for everybody,” Bal-Halpern said, “We know how to do that; there are guidelines for how. Most universities say they are, but are they really following those guidelines? I doubt it.”
Antisemitic incidents in the US decreased overall in 2025, but violent attacks targeting American Jews remained at alarmingly high levels, according to the ADL’s latest Annual audit report. While antisemitic assaults increased by just 4 percent, from 196 in 2024 to 203 in 2025, perpetrators increased their use of “deadly” weapons by nearly 40 percent, the ADL said. Incidents of assault involving a deadly weapon increased to 32 in 2025 from 23 in 2024.
The advocacy group noted that the upward shift was reflected in the shocking murders of Jews in antisemitic attacks in the US for the first time since 2019. Two Israeli embassy staffers — a young couple set be engaged — were shot dead in Washington, DC last May, and weeks later a firebombing in Colorado claimed the life of an octogenarian. In both crimes, the alleged killers cited anti-Zionism as their motivating ideology.
Yeshiva University’s “Antisemitism Conference” was the first step toward amassing even more empirical data on this subject, another conference participant said.
“For all of us who are embarking on this area of research and investigation, we’re all dealing with this very large, amorphous, difficult to fully understand but very disturbing phenomena of rising antisemitism or rising anti-Israelism to the extent that there is a connection between them,” said Rutgers University psychology professor Dr. Kent Harber. “We’re trying to get some sense of the dimension and facets of it for our individual work.”
