That 1700s example is something hotly debated by historians and anthropologists. So, I'm not going to touch on it. My point was that humans innately need/want a tribe. Some humans now, use race in place of a tribe. Others use nationality. Some use religion. It's all the same. This was always the endgame. There is no other outcome. You will never be able to move past it. To think so, is naïveté. Because there will always be a group in the shadows waiting to strike and poison the well.

It just doesn't matter, dude. We as humanity deserve to die regardless. As a species we're absolutely useless to this Earth. We're selfish, narcissistic people. We're animals. We make choices based on how it can help our people first, not others. It has been this way since the start of society.

P.S. I will add that, racism is always discrimination, but discrimination isn't always racism. As such, it doesn't matter if it's called racism, or not. It's discrimination rooted from a tribalistic us v them ideology.
