Culture stemming more from race is a big claim that’s hard to prove. There are too many variables that come in to play and you can’t run anything close to a reliable experiment to prove it. Culture is very much influenced by many things like the climate, land, community experiences (e.g. famine, war), religion. Look how much Japanese culture changed after the atomic bomb was dropped on them. They went from samurais to innovators. They run a fiat ponzi just like the rest of the world, but they don’t have a degenerate society. Why is that? It’s not religion because they don’t really have anything like that. Keep an open mind to such things. They’re very complex.

Also what’s stopping you from living with just white people? There are European countries that are still majority white that you can live in. Finland is 95+% white. And you can have a great time paying their 50% tax rate. It’s predominantly white and it still sucks to live there. Personal defense isn’t even a valid reason to get a firearm license 🤷‍♂️

I agree 100% with your post, until you mention Japan lol. No, that didn't happen outside Hollywood sterotypes, the dramatic systemic changes were eight decades before WW2: the Meji "Restoration".
