Southerners "demand" people like cream gravy and humidity.
Southerners claim there are no "jerks" in the south.
You do have one thing right, though...the friendliness of the South is on the wane these days. Why do you think that's the case? I can tell you. I live in central rural Virginia, and I've seen the atmosphere of cordiality decrease as more and more Yankees move in.
As for your own personal pain, suffering, and general sense of being put-upon, I have a solution for you.
Leave.
I'm sure it was the best, friendliest place on earth, before those dratted, unfriendly Yankees showed up. Or perhaps there have always been unfriendly people in the south, like everywhere else.
And actually, I did leave. But don't breath a sigh of relief, I may well come back.
