I'm amused by people who are shocked, simply shocked to find that a black man is friends with someone who resents past discrimination towards blacks and who speaks openly about his resentment.
Perhaps those same people will also be shocked to discover that I am a white guy who has friends and relatives who resent bussing and affirmative action. I've heard a comment or two at family reunions that I have not immediately denounced while storming from the room--perhaps that makes me a racist too.
Whatever we do, we should definitely sweep all these resentments under the rug and never, ever discuss them openly. Any shrink will tell you that it is far better to let resentments fester than to discuss them.
