They'll ban books by people like Bannon or any influential conservative figure who they deem harmful towards their cause. Even milque-toast convservative thought is dangerous to leftwing ideology... because our economics are based in Milton Friedman while there's are based on couch surfing marx .

However, actual Nazi books... Amazon has no problem with those. Actual Nazism isn't politically attractive. It's authoritarian nonsense as despicable as communism(or nearly as).
