I provided the ADL link that outlines his history of inflammatory and anti-Muslim, homosexual and (to be generous) feminist articles posted on Breitbart with Bannon as editor. I can give you the
Guardian article that outlines his hesitation to have his children around Jews. It's pretty easy to find the divorce papers which Politico got their hands on. His ex-wife (one of the three, I don't know which one) said she was told she'd be financially destroyed if she showed up to court. The ADL link has the information about Bannon physically assaulting his wife (I think that was a different wife) and calling her a c___ while choking her - sorry for being redundant. That's not conjecture, that's a fact outlined in a police report that mentions the marks on her neck and arms.
So let's be generous - he's just a wife beating guy who uses his money to threaten his ex-wives because he doesn't want people to know that he doesn't like Jewish people and was the editor of a website who attracted readers by being anti-Muslim, feminist (female IMO but I'm being fair) and homosexual. That last paragraph is fact and the links provide legal and empirical evidence to prove it.
If you'd want that kind of guy advising our President, you have the right to think so. But you have to admit that there's some justification for the millions of people who are not even a little OK with it.
