Speaking as a lifelong resident of the north, in my experience, most of the North doesn't care about the South.
I'm not even really thinking of the regional divide as such, more the general attitude shown in this thread towards areas (this is the amazing thing I think) that vote in the "wrong" way. It's the sort of divisive madness that makes even less sense in America, with it's lumbering-yet-porous catch-all parties, than the rest of the World. And, yes, we're only talking kids and activists here in this thread, but the kids will grow up and the activists may well influence (not individually, of course) wider perceptions of their party. And it isn't as though the obvious immaturity of that way of thinking has prevented the Republicans from playing at it over the past few years, to their great cost. Attitudes like this are both poisonous and addictive.
Yes, I might be reading a little too much into spiteful comments on the interwebs. But I don't think that pointing out that something is wrong, foolish and hypocritical is a bad thing.
People here have not been insulting the dominating political class of the South, except when their insults have been so broad as to make it impossible to miss them.
