Yep. And the most prominent fascist power that wasn’t overthrown externally (Francoist Spain) lasted 40 years until it’s demogogue died. The reason it wasn’t a bigger problem for the world at large was that it was a politically isolated minor power.
The world hasn’t yet seen something like an (openly) fascist modern USA.
Ren faires are just an anacronism stew. Maybe some take historical accuracy seriously, but I’ve been to quite a few and have yet to see one that does. My local one has everything from ancient greece to steampunk Victorians. There’s even a Wok themed after Imperial China where these guys would fit right in. You see more fantasy then historical costumes usually anyway.
It’s just a place for nerds and weirdos to vibe, buy trinkets, drink, eat fair food, and wear cool costumes.
