This is a human brain.
Can anyone tell who it belongs to? No.
Brains look the same, but they are different.
If you have 12 white people or 12 people of every race under the sun, their ideas will be different anyway.
Stupid identity politics advocates claim that if you have a group of white men, they will all think the same.
In reality, you are probably going to get an atheist, a christian, a jew, an athlete, a fat slob, a metalhead, a socialist, a right-wing, a person who likes jazz,.
Individuals are different... so every group is diverse in terms of thought. Identity politics wants us to think that "if you belong to a certain color or demographics, you all think the same, you ain't diverse" and that's complete bullshit.
If you have an alien, a women, a gay person, a straight man, a black man, or whatever, you will still have a wide array of thoughts and feelings, just like you would have with a group of supposedly white men. Diversity is a fucking fallacy.
