Exactly, PulpHerb. It makes zero sense. Every culture would have to be totally alien and I don't think there's a GM around that could do that, and maintain it, for every possible culture out there. One or two, sure, but everything but be completely unique/not-of-this-world?
This is where it goes to straight up lunacy. And what "hurt" does this cause? I mean, if someone uses their game platform to mock a certain culture, ok, call them out on it and make them stop or don't play.
But the mere suggestion that certain game places could be based on real world cultures? This inflicts hurt on someone? We need a term that is more fragile than "snowflakes" any more.
