Thank you for taking the time to write out such a thought provoking comment. All too often movements will rewrite their history to show that their current beliefs have always been their beliefs.

This part very interesting:

>The good news is that if our current pro-racism movement triumphs and the nation re-segregates, there is a good chance that grandchildren of the current generation will themselves dismantle that system as being old-fashioned and not-with-the-times.

Combine this with the ongoing "Great Sort" where people are more and more moving into areas that best conform to their value systems, it's possible that the country will break apart into smaller pieces before there's an opportunity for a future generation to reject the current obsession with identity labels. It's interesting to see how quickly a large share of the population has adopted the primacy of label collecting when for most of my life the phrase "I'm a person, not a label" was common, especially in progressive circles.
