Dave, I've explained before that I don't see blood on my hands if my ancestors did anything wrong, neither do I blame you for what your ancestors may or may not have done to the native Americans.
Everybody is responsible for his own deeds in my view and that's why I'm not going to take the blame for what the Nazis did, I'd rather make sure it doesn't happen again.

That said, AFAIK the Dolchstoßlegende was used by the Nazis but originated from royalists in the german army after WW1, I'm sorry if I sounded like you were a Nazi, that wasn't my intention, I just wanted to point out that your view sounds like a conspiracy theory.
