I am reminded of Edward Abbey's dystopian novel Good News (1980), which I have to admit that I never finished. In the part I did read, however, he has something about the "oldest civil war of all, that between the city and the country."
If Darcey is right, that is what we're seeing here. Her evidence is from Canada, but it sounds all too familiar:
A rural-urban divide? More then possible I think and to test the theory one doesn't have to look much further then the comment sections provided by Canada's own Globe and Mail and the CBC. Both news services think of themselves as being national but their readership tends to be anti-national. Ten minutes of scrolling comments and you would think that rural Albertans are all blood thirsty knuckle-dragging rednecks with guns and the constant tone of the despise gives one the shivers. It can also go the other way and I've been guilty myself of portraying Torontonians as being latte-sipping elitists living in their own filth.
