I've always heard that Appalachian is Elizabethan English, but I'm not the one pushing it (it's the neo-Confederates, which is ironic considering the mountain folk's attitude towards slavery and the Confederacy). Basically, if you aren't advocating the elimination of all legitimate regionalisms then you and I have no quarrel whatsoever.
Hardly. I love accents and languages. My own accent is echoic. I sound pretty much like whoever I am talking with. Some folks used to think I was mocking them. In my youth I picked up languages the same way and at one time or another spoke Turkish (as a 7-9 y.o. kid) Dutch, Asian French, and Vietnamese. I do English pretty well, too. I am especially fond of those particular southern accents I spoke of, the Mississippi and Alabama loveliness- black and white-, of Irish Gaelic, and Vietnamese, all of which I firmly believe to be languages invented long ago by committees of men for women to speak before there were nightingales in the world.
