Forming groups is still important. We need it to find our place in the world. There is no single truth, therefore we argue and fight.

Absolutely. Forming groups defined by commonality is good. Discussions are important to check our own biases and misconceptions. Diversity is key to avoiding stagnation. Conflict can create opportunity for growth.

Not saying anything you said is wrong, btw. Just wanted to state why we still have this stuff.

Good point, adding nuance is important.
