Southerners smile more than other Americans.
There's an ethic that says: 'You don't run off to the church for the sacraments of salvation, you establish a personal relationship with God. You don't run off to the courts for justice, you settle it yourself. You don't run off to labor unions to sort out your work relations, you can take this job and shove it if you don't like what you're doing.'
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.
Maybe we've been brainwashed by 130 years of Yankee history, but Southern identity now has more to do with food, accents, manners, music than the Confederate past. It's something that's open to both races, a variety of ethnic groups and people who move here.
I think there's a suspicion in the South of people putting on airs. You see it in most successful Southern politicians, but you also see it in someone like Richard Petty, who may be a multimillionaire stock car driver, but he's also beloved because he has a nice self-deprecatory way about him.
