Race, Ethnicity, and America

Earlier this month CJay wrote a long post on the topic of race, ethnicity, and American identity.Naturally, the kind of people who believe the (now-discredited) SPLC is the fount of all truth immediately objected to it.This is, of course, a difficult topic because of the hysterical religious zealotry surrounding it, but God has called Christians to maturity, especially in difficult topics such as these.How should we think about this stuff in a mature and godly way?
