I would say that the politically widespread "unwavering support" for a nation very overtly because of their dominant ethnicity, including whilst they're commiting a Genocide along ethnic lines themselves (the kind of thing one would naivelly expect Germans to be especially disgusted at), proved beyond any doubt that Racism in Germany is alive & well all across the political spectrum, from the supposed "left" of the Greens all the way to the far-right.

(AfD really is just the same mindset with the addition of "If it's good to unwaveringly support them no matter what they do, then it's also good for us")

Sadly whilst the symbols were forbidden, the way of thinking about other human beings (of seeing people as members of ethnicities and judging and treating them differently depending on ethnicity) that was the foundation for Nazism never actually died in Germany, they just changed who the ubermenschen and untermenschen are and don't actually say those words out loud.

I still have the hope that people see the trainwreck the US is now and go "oh shit", and try to avoid it
