Extreme Black Hebrew Israelite Movement

The newest report from the Simon Wiesenthal Center’s Research Department presents an overview of a worldview, ideology, and rhetoric of extremist elements in the Black Hebrew Israelite movement that fans the flames of anti-Jewish hate and - like some white extremist movements - literally presents Jews as the devil incarnate, spawning targeted violence, mayhem and even murder of Jews.

Combating History's Biggest Lie:

Holocaust Denial in the Twenty-First Century

Simon Wiesenthal said, “the history of man is the history of crime.” Holocaust Denial began not after World War II but during the War with the Nazi masterminds of the Holocaust themselves. Fearing what awaited them in defeat, they sought the total destruction of the documentary evidence of the regime’s crimes. Well before Hitler retreated into his Berlin bunker, his henchman tried to eradicate all proof of the “Final Solution,” even as they strove to complete the destruction of Europe’s Jews. SS Leader Heinrich Himmler instructed his concentration camp commandants to destroy all signs of mass extermination in the most audacious coverup attempt in the history of crimes.

Digital Terrorism + Hate 2021

The SWC called on the Big-Five social media giants to refocus on degrading the marketing capabilities of bigots, anti-Semites and terrorists – foreign and domestic.

Not a single mainstream nor emerging social media platform earned an ‘A’ grade in this year’s assessment.

Among the “Big Five,” Facebook/Instagram, Twitter, and YouTube/Google have all received a “B-”; combined audience amounts to almost six billion users.

Other increasingly widespread platforms like Telegram and Parler have received a “D-“ and a “D,” respectively.

The worst grades have gone to the networking sites AnonUp, Gab, and 8Kun, as well as the video platform Brighteon, all of which receives “Fs.” These sites provide a full menu of social media options for extremists.

Louis Farrakhan - Four Decades of Bigotry
In His Own Words

This report was prepared amidst an unprecedented national reckoning about past and present racism.

Deadly New Virus Intersects with History's Oldest Hate

By now everyone is painfully aware that the twenty-first century lacks immunity to not only contagious diseases but ancient ideological plagues like anti-Semitism. The current moment is particularly dangerous because of new efforts to harm Jews by exploiting well-founded concerns about the Coronavirus. This essay puts under the microscope current examples of the threatening conjunction of anxieties about this new virus with thousand-year-old prejudices demonizing Jews not just as Christ killers and Shylocks but as disease purveyors. COVID-19 is a novel virus, for which there is still no vaccine like that invented by Dr. Jonas Salk to end the scourge of polio; but the manipulation of such pandemics by anti-Semites has historical roots going back millennia. Our focus will be the highly-relevant history of what might be called “medicalized” anti-Semitism.

  Decoding Hate: A short guide to extremist codes, symbols + images

Extremists have long utilized codes and symbols to spread their messages to followers. Often these codes are used in place of language and images that might draw more negative attention from mainstream audiences.
