Sure tribalism has also significantly hurt and destroyed some cultures, but it has helped ridiculously enormously more than it has harmed. That's how literally everything works: It will do some cost and some benefit. The benefit however, has far outweighed the cost.

Show me the thing that has only benefits with no downsides, or the thing with only downsides: It does not exist. You're a complete child if you think it does.

But I don't expect you to understand such nuance, you clearly think it's all black and white and either purely good or purely bad lmao. Not worth my time either, go live in your simple world of simple beliefs and simple evaluations. It's your loss not mine. I see no reason to respond further either, I just home you one day learn that the world is actually complex with costs and benefits to everything, even - shocker - tribalism.
