1. Motivations: Many people don't understand why anyone would have lied about exterminations of Jews. When a motive is presented for the lie, more people will be willing to consider they've been lied to. The Holocaust story is a massive bonanza for Jews worldwide. Financially, the payoff has been in the billions, and continues unabated. Psychologically, the story has the effect of giving a blank check for Zionist behavior around the world.
2. The concept of the Big Lie: Everyone should read the excerpt from Chapter X of Mein Kampf where the author explains how a massive lie will be believed simply because ordinary people cannot comprehend that such a huge, oft-repeated story can be anything but true.
-Mein Kampf Chpt. X"In this they proceeded on the sound principle that the magnitude of a lie always contains a certain factor of credibility, since the great masses of the people in the very bottom of their hearts tend to be corrupted rather than consciously and purposely evil, and that, therefore, in view of the primitive simplicity of their minds they more easily fall a victim to a big lie than to a little one, since they themselves lie in little things, but would be ashamed of lies that were too big. Such a falsehood will never enter their heads and they will not be able to believe in the possibility of such monstrous effrontery and infamous misrepresentation in others; yes, even when enlightened on the subject, they will long doubt and waver, and continue to accept at least one of these causes as true. Therefore, something of even the most insolent lie will always remain and stick - a fact which all the great lie-virtuosi and lying-clubs in this world know only too well and also make the most treacherous use of."
Hitler may not have been the greatest author, but he nailed this one pretty good. How ironic that the Holocaust story has become the greatest Big Lie of the present day.
3. Torture used at Nuremberg Trials: The greatest argument in favor of the Holocaust is that "the Germans admitted it." The best response is to point out that the Nazis who "admitted" the Holocaust at the war crimes trials were tortured by their (mostly Jewish) interrogators, usually by having their testicles crushed. Everyone understands what torture is, but few can believe it would have been used by the Allies on war criminals. This is documented in Butz's book
4. The Katyn Forest Massacre: That numerous German officers were hung for the murder of thousands of Polish nationalists by Stalin's NKVD demonstrates the fraudulence going on during the war years. President Roosevelt deliberately covered up the evidence of who really committed the crime. That such corruption could have been going on in high levels of the US government during the war years proves that we should not believe any of the official evidence of the Holocaust
