The reason for Jews taking sh** is because they are incredibly resourceful & successful. Why do someone with such a small population have such huge comparative success. From Entertainment to Science, look @ these folks. They are really intelligent top people. All Fed Chairs recently are Jews - They control Banking etc.
So it is natural to develop some anguish against a community with say 1-2-3% of the population but having large parts of power & having disproportionately high economic & political power. People look for excuses & faults for their own failures & thus Jews are a natural target. It is worse because Asians are possibly more educated & stay away from power circles comparatively while many Bankers, Lobbyists, Donors tend to be Jews.
Anyways @ Topic - Bannon is disgusting. This isn't surprising, What did people expect from Breitbart - Trump should grow some balls & do something, why doesn't Kushner speak to him?
That's a big part of it, but the root of anti Semitism is that they have this religion which says they are chosen and isn't very open to outsiders. Anyway, Jewish power is on the wane. Most American Jews are either liberals or neocons, and both groups are losers this year.
