The Anti-Defamation League, one of the most prominent Jewish advocacy and anti-hate organizations in the US, removed over a thousand pages of extremism research from its site on Tuesday night following online backlash from rightwing influencers and Elon Musk. The ADL’s now-deleted “glossary of extremism” contained over a thousand entries that gave background information on groups and ideologies connected to racist, antisemitic and otherwise hateful incidents. Its pages on neo-Nazi groups, militias and antisemitic conspiracies now redirect to the landing page for its extremism research. “With over 1,000 entries written over many years, the ADL Glossary of Extremism has served as a source of high-level information on a wide range of topics for years. On Wednesday, Musk continued to post about the ADL and reiterated his claim that it was a “hate group”.
