Your article is very well-written. The measure of its quality is that it spurred a number of high quality comments. I think you should celebrate those comments rather than be defensive. You wanted to create an exchange, I assume, and you succeeded.

The one gut level, personal reaction I had to the article (which may not contribute to the conversation) is that it did not address (sufficiently) the humanness underlying tribalism/racism. Although I am white, for some reason I have spent much of my life in the world of people of color (civil rights trial lawyer, coach, teacher, lover of jazz). That did not give me any special knowledge about the non-white experience, but it made me care. On those occasions where what you call reverse racism was directed at me, it always hurt. I understand the source of the anger, but the exclusion still hurts and separates . . . not because it came from a black person, but because it came from another human. No one wants to be excluded, and it never heals.
