We had stable nations long built on populations of mostly kin. It took a really long time to get here. We don't have that anymore because someone really likes using whacky woke wanker terms like white/black/brown. We're populations not colors. Broad population mixing always causes major shit and seemingly no one can ever address that because they're still using the same words they got from NPC TV.

If you bring together mutually incompatible populations then expect major civilisational division and instability. That's nothing to do with garbage black/white/brown labels. It's inter population warfare
