I have an inability to detach the sound of a southern accent from the notion that the person with whom I am speaking is uneducated. Sorry 'bout it. Blame the Yankee-owned/operated media, but I'll credit my first-hand experiences.
I've spent the last few days driving through Arizona (lived there 3 years), New Mexico, 900 miles of Texas, Louisiana, Mississippi, Alabama, Georgia, Tennessee, West Virginia, Virginia, and Maryland. While I experienced southern hospitality in the form of a Virginia sheriff helping me retrieve my keys from my locked car outside a Waffle House at midnight, the waitresses in a different Waffle House were incapable of adding together whole numbers below 5. They added together $3, $4, $2, $2, $1, etc to less than $9 total.
I believe people in the southern states to be generally less-educated and, as a result, less capable of functioning in society.
All of this being said, you should probably get a sarcasm detector or recognize that, if no one else, the professors at southern universities have educations and are entirely capable of putting grades online in a timely manner, assuming the TAs and preceptors hold up their end of the deal.
