I don't know. The Waffen SS was pretty much the elite arm of the Nazi Party - entering it meant being above-and-beyond the usual call. I would say that members of the Waffen SS were, if not war criminals, certainly bona fide Nazis that do not deserve to be lauded in any way. I don't necessarily agree with pulling the show, mind you, but I do think it should be used to teach a lesson, as well.
I could say a lot about the inability of the American school system to teach history, but it's so patchy based on the way the several states teach that there's no real uniform criticism, other than to say "Americans teach all history as American history."
