This is the first I’ve heard of it, but here’s one of his infamous quotes:
"There is a trait in the Jewish character that does provoke animosity, maybe it’s a kind of lack of generosity towards non-Jews.
I mean, there’s always a reason why anti-anything crops up anywhere; even a stinker like Hitler didn’t just pick on them for no reason.”
His other quotes tend to be condemnation about specifically Israeli zionism and barbaric murder, but i don’t have context as to whether he’s referring to palestine or not. Some people might have more sympathy for these statements these days, but a lot of his other quotes have to do with Jews controlling money and media, less defensible prejudice.
Well - you kind of answered your own reservation there: He’s a piece of shit rapist. So I believe it’s safe to say his main character traits are probably not defined by the religion he was born into, which makes it not quite so weird to me, as I generally do not try to rationalize behavior of people who have otherwise proven a complete disconnect from ethical norms.
