Diversity programs are still necessary. Companies should go out of their way to hire blacks because so many go out of their way to not. And Republicans don't want to do anything about that. Let the free market decide.
So blacks don't vote for you because of such policies.
My view is that the vast majority of employers, have formal and informal policies of "going out of their way to hire or promote blacks", as you and your brother and I have often witnessed.
It is worth noting, that having this disagreement between us, is an honest disagreement about what other people are doing. IT is NOT a belief of anything about blacks being wacially inferior, or what have you.
It is thus a valid political disagreement. It is not wacist.
That blacks vote for those that want to increase discrimination in their favor, does not make Republicans wacist.
