That super weapon was the gas chamber. They proceed to assert that not a single human being was gassed to death by the Nazis. Gassing, they argue, was purely used for disinfection. Only thousands of Jews died during the Second World War and these perished as the unfortunate victims of the exigencies of war, mainly at the end of the conflict. There was no policy of genocide.
Holocaust denial is deliberately misleading.
It focuses exclusively on gassing as the sole means of murdering Jews, when there were a series of other methods. The einsatzgruppen , or mobile SS killing squads, followed the German army as it advanced eastwards, and engaged in mass shootings which claimed the lives of well over one million people. The deniers do not speak of the crowding of Jews into ghettos or of the labour in the concentration camps, and the deaths that resulted from starvation, disease, and brutality. The deniers, in their questioning of gassing, deal only with Auschwitz , which was both a slave labour camp and an extermination camp. The deniers are silent on the use of gas vans.
