"Researchers at the Counter Extremism Project, an international nonprofit policy organization, said the National Socialist Movement (NSM) is one of the organizers of the day that has been promoted through social media platforms."

"The Counter Extremism Project (CEP) said that it based on its monitoring of the Telegram instant messaging service, 'the participants are identified as the National Socialist Movement, two regional active club chapters in Iowa and California, and a small New York-based group.'"

"An analysis of social media activity by the Counter Extremism Project (CEP) found that the call to action stemmed from accounts associated with the National Socialist Movement, and three regional extremist groups based in Iowa, New York, and California."

"On Thursday, researchers for the Counter Extremism Project found that several neo-Nazi groups had coordinated the 'Day of Hate' on the messaging platform Telegram. 

On the app, the National Socialist Movement, a prominent neo-Nazi group based mainly in Iowa and California, encouraged other white supremacist groups to 'send photos and videos of antisemitic rallies,' the project said."

CEP Senior Advisor Ian Acheson writes: "Shawcross found a prevalence of ‘extreme antisemitism’ in the Channel cases he dip sampled. What’s striking is that antisemitism is an equal opportunities hatred. It is mobilised by extreme left, right and Islamist ideologues and their followers. Perhaps this explains a pre-eminence of obsessive, ‘fanatical’ violent hatred towards Jews in the cases he examined – behaviour that included the professed desire to murder and bomb Jews and the burning of synagogues."
