The Holocast is a historical fact and has been proven many times over, your heroes, the nazis even admitted it. If you or one of your neo nazi pals wants to say it didn't happen, YOU have to offer proof. And, of course, you have got nothing.
I think that you know it happened. But it is terribly inconvinient to your nazi ideology so you pretend that it didn't. Can't have the jooos being victims can you?
