I sincerely don't think either of the two sides is advocating for those things (ignoring a very few extremists - on both sides - with malicious intent, who don't represent the majority).
I do see those issues mentioned a lot in the public debate, but mostly in the context of straw man arguments repeated as a sort of battle cry, and to denigrate "the other side".
It was a whole lot easier to push McCarthyism than it ever was to convincingly prove you weren't a communist.
