Anti-intellectualism has a certain tradition in the USA, it’s kind of well-known.

A German perspective: I think Germans have always been this stupid, they’re mostly just more willing to say the quiet part out loud than they were between 1970 and 2014 (rough estimate). The difference is that the far right extremists have a popular platform now, and the mainstream parties refuse to ban either the far right party or all the media (X, Facebook, local tabloid press etc.) that’s pushing them. If this party had been around in 1960, it would definitely have been banned.
