To roughly sum up your question about NC: http://www.newsobserver.com/opinion/op-ed/article122593759.html
(also, after reading some of y'alls responses after scrolling down a bit: I mean, to focus on the South as a racist region does a disservice to the truth that the country is racist. When one travels throughout this great land, you'll find monuments and markers noting few of the struggles peoples of color/different religions/sexual orientations/gender have dealt with or are currently suffering under.)
The South was being focused on as having it's own nationalism and a particular revisionist history regarding it. Not racism.
–- Update From New Post Merge ---
Poorly educated people living in rural areas voted overwhelmingly for Trump, yes. The overwhelming majority of people who fit that description are white, but their views are clearly the result of their environment, not their race.
Attaching a racial label to an ideological group is very dangerous.
There's been five billion posts talking about rural whites or post-industrial blue collar whites since and before the election.
Did you just hard-reset and forget this so you could get some extra pearl-clutching in?
