Historical Revisionists don't deny that Jews were persecuted. There were concentration camps, and Jews were sent there where many died of starvation and typhus. They were not gassed to death, however, and the 6 million figure is grossly impossible even on a practical physical level.
"Fred A. Leuchter is America's leading specialist on the design and fabrication of execution equipment, including homicidal gas chambers. In 1988, Leuchter scraped samples from the alleged gas chamber walls in Auschwitz, Birkenau and Lublin. Cyanide residue would be clearly evident on all these walls if gassings did occur. To his astonishment, Leuchter found no significant cyanide traces in any one of these rooms.
In 1991, the Polish government repeated these tests to disprove Leuchter's findings, but they as well found no evidence of any gassings ever occurring.
The structural integrity of these "gas chambers" is also extremely faulty. These rooms have ordinary doors and windows which are not hermetically sealed. There are large gaps between the floors and doors. If the Germans had attempted to gas anyone in these rooms, they would have died themselves, as the gas would have leaked and contaminated the entire area. There are no provisions to prevent condensation of gas on the walls, floors or ceilings. No exhaust stacks have ever existed.
Though six million Jews supposedly died in the gas chambers, not one body has ever been autopsied and found to have died of gas poisoning. We have been shown piles of bodies from World War II, but most of these persons died of typhus or starvation or Allied bombings and a great many of those were murdered Germans, not Jews." -Mark Weber, associated editor of the Journal of Historical Review
