I didn't disagree with you, I just put it in a way that is more digestible to people who are sick and tired, yet aren't all in on the same beliefs we tangentially have. Balkanization would require trade. Will you trade with blacks and hispanics? I don't think it's unreasonable on paper but in practice, you can't just tell some people to go over there and others to go somewhere else while you bring everyone to one particular area. It would be a logistical nightmare.
