Unless you are talking specifically about the western part of the state, you couldn't be more wrong. Most of rural NC has a very high African-American population - higher than the state or country average.
As someone with deep roots in rural NC I find your statement to be untrue. Perhaps the company you chose to keep was that way, but it is not my experience. I'll put my rural NC bona fides up against anyones. We are not all anti-semitic racist hillbillies, whether we graduated from UNC or not.
With statements like the ones you made above, is it any wonder that Duke fans are seen as elitist? Calling folks racist andanti-semitic with no proof or reason is hardly worthy of this board.
