Looks to me like harmless Halloween costumes for big kids but it often seems that the prevailing thought today is that every white southerner was an Ashley Wilkes, every girl a Scarlet O'Hara. The real Confederacy was ugly, rotten, dishonest and needed to be beaten for the good of all Americans of all races.
Oh please, if we'd discarded the founders from Virginia and points south, Hamiltion would have nationalized the banks and carriage makers over two centuries ago. While slavery might have been, they weren't ugly, rotten, and dishonest, it was a national failing, not far out of step with the times. From your picture I'd hang with the kids on the left any day.
