I'm not sure what your post is trying to say. David Irving is an English historian who relies on legitimate historical documentation. Early in his work he assumed that the holocaust story of mass extermination and gas chambers was based in fact. The more he found, the less he believed. To my knowledge, he has become a firm skeptic over any kind of "final solution" and any use of gas chambers. He does not deny that many Jews died due to the hardships of forced labor, most notably disease, as did many in other groups. Nor that there are examples of group executions, though the 6 million figure is ludicrous.
