• The Anti-Defamation League tracks the incidents through news and media reports, government documents (including police reports), victim reports, extremist-related sources and the Center on Extremism investigations, according to a "Frequently Asked Questions" section on the ADL's website.

  The Anti-Defamation League's interactive map includes information on incidents involving anti-Semitism, white supremacist propaganda, white supremacist events, extremist-police shootouts, terrorist plots and attacks and extremist murders.

  Along with providing the first-of-its-kind interactive and customizable map detailing extremist and anti-Semitic incidents around the nation, the ADL also provides information on the annual quantity of white supremacist propaganda that gets spread throughout the country.

  The Anti-Defamation League's Center on Extremism reported 2,713 cases of circulated propaganda by white supremacist groups in 2019, compared with 1,214 cases in 2018.

  Oren Segal, director of the League's Center on Extremism, pointed to the prominence of more subtly biased rhetoric in some white supremacist material, emphasizing "patriotism."

  By emphasizing language "about empowerment, without some of the blatant racism and hatred," Segal told the Associated Press, white supremacists are using a "tactic to try to get eyes onto their ideas in a way that's cheap, and that brings it to a new generation of people who are learning how to even make sense out of these messages."

  The Anti-Defamation League, which was founded in 1913 to combat anti-Semitism as well as other biases, describes its mission as "to stop the defamation of the Jewish people and to secure justice and fair treatment to all."
