The Holocaust happened as we know from all sorts of video and written evidence as well as by eye witness accounts of those who did the persecution and of those who survived. So any attempt at denial just serves to pinpoint the bias and crazy mind set of the one who is doing it for his own purposes.
David Duke's denials of the Holocaust are not supported by any real existing evidence. David Duke is someone who is delusion to reality and also doesn't seem to understand that not many people side with him. He may feel he represents American ideals, but nothing could be farther from the truth.
David Duke is a known racist and no one in the mainstream pays any attention to his claims. There is abundant evidence that the Holocaust was real. Many people who deny the Holocaust are racists who are seeking to attack the legitimacy of Israel. No one listens to David Duke.
David Duke's denial of the Holocaust is not supported by existing evidence. I believe that the Holocaust happened and it was a tragedy for the people that were in those camps. I think that David Duke just wanted some publicity by making remarks that he could not prove. I think he was lying about the whole thing.
No, David Duke's denial of the Holocaust was not supported by existing evidence, because there is clear evidence that the Holocaust happened. David Duke is not credible, because millions of Jews in Europe did not just magically disappear on their own. Mass graves have been found and there are eyewitness accounts. The Holocaust happened.
