(JTA) — More than 100 Jewish activists have signed a letter appealing to major advertisers to end their relationship with X, the platform previously known as Twitter that is owned by Elon Musk, calling it “a breeding ground for antisemitism” that “represents one of the largest dangers to Jews in years.”

The signatories are also calling on Apple and Google to remove the platform from their app stores, which would effectively make X’s app inaccessible to the vast majority of mobile users.

The call, issued Tuesday, comes after weeks during which Musk has interacted with white supremacists and written a stream of posts attacking the Anti-Defamation League, the Jewish civil rights organization that has criticized his removal of hate speech guardrails on the site. The ADL also called on advertisers to pause their spending on the platform last year, and Musk has threatened to sue the group for, in his view, tanking X’s ad revenue.

“We have watched in horror as a new stage in antisemitic discourse has spread like wildfire on one of America’s largest social media networks,” said the letter, spearheaded by Elad Nehorai, a progressive Jewish activist. “All of this has been facilitated and enabled by its owner: Elon Musk.”

Many of the more than 120 signatories are progressives, among them cartoonist Eli Valley and Ruth Messinger, the former Manhattan borough president and onetime Democratic nominee for New York City mayor who later led the American Jewish World Service, a global aid group.

But a number of prominent Jewish thinkers and activists from across the political spectrum have signed on as well, including David Hazony, a conservative editor who just published “Jewish Priorities,” a collection of essays; Archie Gottesman, who sits on the board of the Democratic Majority for Israel and co-founded JewBelong, a group that aims to combat antisemitism and reinforce Jewish identity; and Rabbi Yitz Greenberg, a longtime leading Orthodox Jewish scholar. The letter was also signed by Rabbi Rebecca Sirbu, the executive vice president of the Jewish Funders Network, and Rabbi Isaiah Rothstein, a scholar and public affairs adviser at the Jewish Federations of North America, though neither listed their organizational affiliations.

“We are alarmed by his targeting of the ADL: not because of our views of the organization (we represent a wide range of views, including some who fundamentally oppose the ADL as well as staunch supporters), but because of the way he has used the organization as a very clear stand in for an antisemitic representation of Jewish power,” the open letter said.
