You destroy a culture by importing another one.

Didn't work out so well for the natives way back in the day 😀

No, it did not lmao. Still, I wonder why they were so ruthlessly driven out when it probably didn't need to be that way.
Seems to be built into us at the base level. I certainly want culturally aligned folks all around me, so I get the fences and neighbors stuff, but I also want to be on the "good karma" team. Glad I'm I'm charge ha...
Cultures need to learn from each other. They should be allowed to do so from a distance if they so choose and can arrange their private property and contractual associations in such a way as to do so nonviolently. Anything else is illegitimate. Governments fuck this up for everyone.
For real. Good fences make good neighbors, and if you tear down the fences and mix everyone up, suddenly you've broken everything.
Like tossing all your organs in a blender and saying you can function even better like that.
I like multiculturalism, although not all aspects of different cultures are compatible with each other… take the good things that will last
Large, homogenous cultures are strong together and harder to conquer. A collection of strong but largely incompatible cultures with strong borders makes for a stable world.
