As I said in a sibling comment, I view race as too broad a concept to usefully generate social identity, and the fluidity of the concept makes it slippery to deal with. Your second point is a good one, I will think more about it. That said, it seems to me that in the long run relatively homogenous populations (really, many smaller politically independent homogeneous populations, as well as politically independent hetrogeneous populations for the smarter folks) is the best way to maximize social identity and minimize conflict. By the way, I appreciate you taking the time to thoughtfully respond to my comment. It is difficult to say what I think may be the truth (with, I hope, no maliciousness) in todays environment, so thank you.
