My family were at a reenactment at the Atlanta History Center and witnessed the curator argue with and turn away a black Confederate reenactor. The reenactor told them his ancestor had fought for the South and they basically told him he was CRAZY! We had dinner with him at Johnny Rockets later and he had a wealth of info to share with our children and us about a subject we knew nothing about...Black Confederate Soldiers.
Atlanta History Center=PC History ONLY
Atlanta is interestred in nothing but revision. I'm supprised the confederate soldiers in the reenactment you spoke of weren't forced to wear hoods.
