If you care to define the South as a poor, rural region with lousy race relations, that South survives only in geographical shreds and patches and most Southerners don't live there any more.
I do believe states' rights was a sound doctrine that got hijacked by some unsavory customers for a while - like, 150 years or so. I'm professionally obliged to believe that knowledge is better than ignorance, but some kinds of forgetting are OK with me.
Southerners smile more than other Americans.

Every Southerner, I think, knows people like Bill Clinton, maybe not quite as smart and maybe not quite as liberal, but kind of a glad-handing, country-club yuppie Southerner. The problem is we don't have labels for middle-class Southerners.
The South is like my favorite pair of blue jeans. It's shrunk some, faded a bit, got a few holes in it. it just might split at the seams. It doesn't look much like it used to, but it's more comfortable, and there's probably a lot of wear left in it.
