Well I have personally read transcripts from statements Bannon made before the United Nations, and it is clear that he holds very extreme views that can be summarized as such -Christian white men are the only people in the world who have any redeeming value and everyone else, in the entire world is a problem. So, he wants all else eliminated. That is the gist.
“Dick Cheney. Darth Vader. Satan. That’s power. It only helps us when they get it wrong. When they’re blind to who we are and what we’re doing.”
That’s a Bannon quote. So no, maybe not white supremacists, because that doesn’t quite capture what he is. He is something much worse, than a white supremacists. These kinds of purveyors of vast systematic destruction of other people and other belief systems, are the darkest of all, connected to an evil so deep and ancient, probably the best word for it (from his own mouth) is satanic or inhuman.
