I hope you forgot the sarcasm tag...because that’s about dumbest thing I have read here in a while...
...or you really think southerners are that backwards and ignorant...
I have family from that area. The old families that haven’t been broken up and scattered to the wind maintain the memories of their ancestors and what they did and what happened on their land. The memories of the depredations on the families who’s men were off to the war are especially remembered. If it’s ‘New Speak’ to say knowledge of the past is ignorance and learning lessons from that knowledge is backwards then so be it (or is that Soviet?(recycled 50s joke there)).
