The problem is that most of arguments have very little factual basis in the first place. "We live in a system of white supremacy" is not even really an argument. It's just his opinion that you either agree or disagree with. I don't agree with that because he tries to make "white supremacy" an all-encompassing and omnipresent boogeyman that we can blame all of our failures on.
He doesn't go that far. However in this integrated society, there is a clear bias in favor of white people. To deny this is simply being disingenuous, or you're a simpleton who can't see it.
