One thing I read in Sapiens that has stuck with me is that a natural group/tribe size is only 40 or so. Anything above that needs a common belief/god or a common enemy. God/religion served that purpose for a long while, then philosophies like communism/capitalism/marxism/liberalism/conservatism, etc. took over. Hitler/nazism is an example of a common enemy uniting people. More recently, and more relatable, you can see how lemmy itself grew exponentially because of the common enemy reddit. All this to say, tribalistic behavior can never be overcome as far as homo sapiens are concerned, because that is what defines us as a species.
