Anti-immigrant fervor, once relegated to more extreme quarters, has been increasingly mainstreamed over the last ten years. Over the last two years, with the advent of a new administration focused on much stricter immigration policies and complementary executive actions, anti-immigrant and anti-refugee sentiment has made life substantially more difficult for all immigrants.

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.
Over the past decade, domestic extremists of all kinds have killed at least 372 people in the U.S. Of those deaths, approximately 74% were at the hands of right-wing extremists, about 24% of the victims were killed by domestic Islamic extremists, and the remainder were killed by left-wing extremists.
In 2021, domestic extremists killed at least 29people in the United States in 19separate incidents. This representsa modest increase from the 23 extremist-related murders documented in 2020 but is far lower than the number of murders committed in any of the five years prior (which ranged from 45 to 78.)
White supremacist propaganda, which allows extremist groups to disseminate hateful messages and gain attention with little risk of public exposure, has been on the rise for several years. In 2021, the overall numbers were down slightly, but paired with a 27 percent increase in antisemitic content and messaging.
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.
