The human condition is complicated, and the human brain is a pattern matching and association machine.
Humans have been identifying and separating themselves by color/race since the beginning of time, even before we could talk. It is the first category... before rich/poor, beautiful/ugly, young/old, etc. It's almost primial.
The context to what I wrote was in relation to the current "white privilege" PC bullshit that has been indoctrinated into our collective. Nothing more.
How exactly does proving that something has always existed also show that it is right?
Can't it just be an evolutionary survival mechanism?... One of the things that primarily is designed to help people come together and stay away from danger.
I'd imagine at the core of it there is a neural network (that you're born with) that categorizes things into - "like me" - "not like me".
In of itself, it's not something that's right/wrong in a moral sense, but how it's further consciously used can be.
