Would someone who is downvote-burying these comments care to explain their distaste? Irrespective of whether you agree with Sowell's viewpoints, they are articulate and seem germane to the conversation.
The distaste is a black man who is a republican. That is all there is to it. Ask any non-white republican, and you will understand. The hate dished out towards us is on a level white republicans never see (not that they should... it's absolutely ridiculous). Accusations of 'Uncle Tom', 'race traitor', etc are common. When the various racial groups organize anywhere, and you volunteer your time with them, they silence you, get rid of you, and prevent you from speaking up elsewhere.
