My own two cents, I spent a good chunk of my childhood in the middle of nowhere Georgia, and have actively suppressed Southern-isms in my vernacular. I associate it with a time in my life where I was at the whims of people whom had neither my best interests or even their own at heart; trapped within a culture that promoted ignorance and blind fanatical devotion to evangelical hucksters. I can appreciate that this experience may not ring true for everyone from the south, and that there are plenty of southerners that don't conform to outdated values.
Nonetheless, I can't say I'll be sad to see it go.
