First two aren’t really an argument.
Culture is not fluid. It’s only fluid to people like you who see a stable society and try their hardest to find weak points to enter through. Cultures fall to subversion, they fall to dishonesty, and they fall to demographics. That’s why somehow people keep resisting progressive politics all over the world, most people don’t want it, most people don’t care. You have to weasle your way into their cultures and governments, beat them over the head with lies for generations, and force it on them while rewriting history to pretend you didn’t…
I definitely wouldn’t want to have had Germany as an ally in WW2 because there shouldn’t have been a WW2 and if it had to happen I’d wish we’d have never gotten involved. Still, no, Americans didn’t care about it. Hollywood did though because it’s always been an industry of propaganda.
Yes, change is very slow. As stated, you gotta beat people over the head with propaganda for generations to get your way. You have to change history to guilt them into hating who they are and what they have. The world shouldn’t be a better place for everyone, that mentality is how we brush off grooming gangs and sex offenders dressing up like women and rolling around with kids in a library. That’s how we ignore obvious signs of degradation and collapse.
