Oh man, there is so much to unpack here. We have been well past the tribal stage for millennia now, so I don't really get your point here. And yes it was a social construct, not all animals are tribal. Great apes have very different social structures and behaviours regarding other groups, just compare chimpanzees and bonobos.

Human history is full of examples of overcoming tribal structures. The fact, that people from all over the world write English on platforms like lemmy is proof that it can't be that important to stick to your "tribe" (I think you mean language group?) and exclude others.

And no, most europeans did not speak English well enough to take part in deeper conversations until very recently. We are getting there though and it's absolutely noticeable when you look at YouTube content, subs and conversations on reddit, cultural products like music (compare the languages of the ESC now vs. 30 years ago).

I also don't get what you mean by "identity". Why can't European, world citizen or human be an identity? National identities are just as manufactured as others would be.

And by "content" I'm obviously not talking about tiktok dances in hardware stores. I'm talking about what OP posted, critical analysis, politics, opinions.
