the advantage here is that, unlike blue/red tribe mapping, it's based on actual cultural movement that exists and isn't cringingly racist, so you're already ahead of the game
I'm happy to make it red / blue / gray / brown ...but even that is North America centric. What's relevant re brown in NA context is meaningless / lost in other details in, say, Pakistan vs India vs China context. Always thus - a general model has 20,000 tribes.
