Each year, ADL’s Center on Extremism tracks murders perpetrated by all types of extremists. In 2018, every single extremist killing — from Pittsburgh to Parkland — had a link to right-wing extremism. This report provides key insights into the crimes, including motivations behind these violent attacks.
In January 2021, ADL investigated how a variety of platforms address Holocaust denial content. Our investigators both reviewed policies and tested enforcement regarding Holocaust denial. We created a report card on how tech companies are currently managing Holocaust denial content on their digital social platforms based on these results.
In the days following 9/11, antisemitic conspiracy theorists dismissed the widely accepted version of events, instead crafting alternative narratives directly implicated Jewish people and Israel in the attacks, peddling antisemitic tropes about Jews supposedly manipulating word events for their own benefit and at the expense of others. Twenty years later, these antisemitic 9/11 conspiracy theories continue to thrive.
