I agree to a point. Those are all modern migrations that you cite. How much of today's interpretation of the Constitution allowed the behaviors to migrate with the people (people using the laws to force the "natives" to comply)?

How has mass migration changed regions in the 18th and 19th centuries? Didn't the unpopulated western territories form around like-minded ethnic settlers dominating different regions? Didn't foreigners emigrating from Europe in the early 20th century settle in cities and neighborhoods already dominated by their fellow nationals?

It seems to me that the second half of the 20th century was Americans relocating to other regions and changing those regions, rather than outsiders relocating and then assimilating.

Correct. Look at New Hampshire voting for Obama, Vermont going for gay marriage and Washington state going so "green" it's impossible to do business.
