>Which is quite bizarre, when you think about it. In a country as systemically racist and white-supremacist as the US*, one would think such a following would be a boon, not a liability.

Yeah, it is to about half the country. Are you daft or what? Look at Trump Jr's instagram... It's just memes about culture war nonsense, including this kind of jewish crap. It is a boon to those folks. Trump won his 2016 campaign on it and came pretty close in 2020 as well.
