I've lived in three out of the four states listed here (and in the case of Florida, lived in a predominantly Jewish nabe for a time), and can tell you that the closest thing to anti-semitism that I hear among my fellow gentiles is about "the rude Jewish ladies at Loehmann's." I can't for the life of me remember any gentile folks who had swastika's in their basements or belonged to the National Alliance.
Anti-semitism these days is confined to Muslims and the American Splendor rejects who live at home with their parents and blame others for their failings.
You didn't go to the anti-war rallies.
Anti-semetism is not coming from just some neo-nazis and muslims, but from college age liberals and their professors.
At anti-war rallies, it typical to burn both an American flag and an Israeli flag, some of the most openly vicious displays of anti-semtism, have come in massive gatherings of left wing activists.
Columbia, which has a serious hatred of jews, had teachers make horrific statements, and after an investigation, those professors, who addmitted all, were cleared.
The Marxists have their theory based on class; the Nazis on race. It's all still socialism.
