Holocaust deniers make the following claims:
Nazis did not use gas chambers to mass murder Jews. Small chambers did exist for delousing and Zyklon-B was used in this process.
Nazis did not use cremation ovens to dispose of extermination victims. The amount of energy required to fire the ovens far exceeded what the energy-strapped nation could spare in wartime.
The cremation ovens that existed would have been too small for this purpose and the reason there were cremation ovens at all was they were put in to provide cremation services for the deaths from natural causes and disease epidemics that could reasonably be expected in a high-density work camp.
The figure of 5-6 million Jewish deaths is an irresponsible exaggeration, and many Jews who actually emigrated to Russia, Britain, Palestine and the United States are included in the number.
Many photos and much of the film footage shown after World War II were specially manufactured as propaganda against the Nazis by the Allied forces.
Claims of what the Nazis supposedly did to the Jews were all intended to facilitate the Allies in their intention to enable the creation of a Jewish homeland in Palestine, and are currently used to garner support for the policies of the state of Israel, especially in its dealings with the Palestinians.
Historical proof for the Holocaust is falsified or deliberately misinterpreted.
There is an American, British or Jewish conspiracy to make Jews look like victims and to demonize Germans.
The overwhelming number of biased academics and historians are too afraid to actually admit that the Holocaust was a fiction; they know they will lose their jobs if they speak up.
Holocaust denial ignores or minimizes the tens of thousands of pages of documentation and photographs prepared by the Nazis themselves that survived the war.
Historians have provided precise responses to Holocaust deniers' claims, debunking their arguments and falsifications.
