That can be empirically proven by those who have a choice as to what “race” they identify as.
It would be obvious that anyone given the choice would choose to identify with the “race” with the most privilege.
When you look at everyone that tries to claim some “minority” status, you see that the privilege enforced in our current society is not in being “white”.
Nobody has been able to explain exactly what this “privilege” is supposed to encompass. So it’s nothing more than a vague catch-all excuse for white success and non-white failure. And the beauty of it, its power, arises from the fact that your very denial of its existence is ... wait for it ... because IT exists!
Marx — and the whole postmodern movement — relies on these tautological syllogisms to immunize themselves against any criticism. “You can’t argue with me because you’re wrong. The very fact that you’re arguing with me proves it.”
In the field of Logic, this is known as “Byproduct of Bovine Digestion.”
