Well, that's interesting.
There -are- some digs at the south. Rhett says at one point (paraphrasing), "the cause of living in the past is dying right before your eyes."
He also says, "All we have are cotton, slaves, and arrogance."
And big Sam says, "we're gonna dig ditches for the sojers to hide in." I remember seeing GWTW as a child and the audience just cracked up at that line.
But Rhett AND Ashley always maintained their honor. That is worth a lot.
I remember seeing GWTW in college at the university center and when Rhett told Scarlett she looked good enough to eat, it almost brought the house down.
