I'm not missing shit by not being familiar with his accomplishments, is what I'm understanding here.

100%. i am not sure how i even learned anything about this bozo. i think it was some kind of "check out this idiot" video, and the only reason it caught my attention was because it referenced The Equalizer, which is my favorite kind of slop movie. having watched it an embarassing number of times, i was like, "he was in that?". definitely hadn't even seen his name/face since i learned about him. funny that he's #1 on any list, but if i had to lay odds my guess is he's a true antisemite and not a maligned antizionist.
