The history behind these men and especially the Civil War has been incredibly white washed and desensitized. This result is not surprising.
Not sure what they teach you guys in Georgia, but some Southerners don't get our history whitewashed. We just don't shame ourselves for what some people's ancestors* did generations ago, unlike the Germans.
*Not all of mine - one was poisoned because he was elected to go to the Arkansas secession gathering, and he made it clear he was not only opposed to secession, but some reports indicate he opposed the expansion of slavery - a very, very radical view considering his time and place, which I think we should consider.
