Jan 6 guys are nothing like a representative sample. Trailer park grandpa couldn't show up to that for multiple reasons. Even then, I'd guess a median age of 45 just based on the videos. The shaman guy was like 32 and he was kind of a baby.
I know less about normal Trump rallies, but I don't really need to because there's actual polling to rely on. MAGA youth exist, but they're underrepresented and even more heavily poor, white, uneducated and rural. Meanwhile, in Europe, there's basically no correlation. Young and old alike support AfD about the same.
What we have on this continent is definitely fascism, fueled by pure, barely-directed hate and hostile to democracy. In Europe, I wonder if it's more of a reversion to Japan-like policy, which might have been more natural for these ancient kingdoms all along. That's just a wild guess, but I hope so, because I like democracy.
