Well I wouldn't say that he believes it to be a full blown hoax, because he says that he doesn't believe that it didn't happen, but that what they teach us in our history books is lies and not everything they teach us is the real truth.
Also, we are never taught that in 1933 the Jews declare a 'Holy War' on the Germans.
So sad how many people are completely brainwashed and don't know how to think for themselves.
"Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned." - Siddhārtha Gautama
