“Who is James Allsup and is he racist?”
Right wing, pro-police, Trump supporter who makes videos for Youtube. Most of the videos I saw were about his experiences on college campuses. I did not know he had joined Identity Europa. https://www.identityevropa.com IE was led by Nathan Damigo last time I checked and he hangs out with, and makes common cause with, Richard Spencer. I would describe Spencer as a soft spoken, friendly sounding Nazi in a tweed jacket.
Per the DSouza info, connecting with Richard Spencer indicates leftism. What a mess
