Why do half the Republicans defend the south, but the other half gloat that the south was Democratic?

Is it a regional divide, where Republicans from the south defend Dixie, say it was about "state's rights" say "The South Shall Rise Again", and have Confederate flags, and the Republicans from further north say "lol, the Confederacy was the Democrats, and so was the KKK"? You can't have it both ways. When you talk about secession like Rick Perry, that obviously fits the Confederate model. When the only music you can get on your side, and that the oldies love, is country, that's telling. When you have Larry the Cable Guy, and demonize intellectual "elitists", well then don't pretend Jefferson Davis isn't your guy. The south may have been Democrats, but they were conservative Democrats, because the roles were reversed back then. Same with the Ku Klux Klan. What's weird is that a lot of these people have the same views as the pro-south contingent, about how old the earth is, religious issues, "elitists", etc, just like the people on Fox News. If the revisionists met with the League of the South, I wonder if they'll consider them Yankees. Half of you support the confederacy, and the other half thinks they were liberals. I don't get it.
