It really has nothing to do with science at all. It's just another way to punish the majority for crimes of their ancestors, and to forcibly give power to a minority for simply existing and being a certain race or gender.

Nobody really wants equality. They want supremacy. If they did have equality, they would be treated like everyone else and lose all of their power/special treatment.

They are also tools of our politicians to be a permanent victim class, so the politicians can dole out justice and get votes.
