How come all hate groups hates Jews?

Why do hate groups like the New Black Panther Party, Nazis, Neo-Nazis or the Ku-Klux-Klan hate Jews? Are they jealous of them because they have good jobs like owning Hollywood or something like that? That would be my only guest. I thought Black People were the most hated race but I'm starting to learn that people (in general) hates Jews. Jews never did anything to hurt anybody, they killed Christ but wasn't Christ a Jew too?
