You are not convinced for some reason other than facts.
Did you read the lengthy article I posted?
It covers your “technical” concerns, and has interviews with Nazi guards, and testimony from war crimes trials.
In any court in the world (even Germany) it is admitted the Nazis used gas to kill millions.
Facts are stubborn things.
I've read many lengthy articles, including yours. They don't all line up with their "facts" - even yours. And no, your article did not completely address all of my technical concerns. I don't care to debate it - you're convinced, I'm not. It has nothing to do with the reality of the holocaust, just one particular method of killing among many. This is not a monolithic subject - "accept it all or you're a denier." Yet that's what it's become, and to enforce it, a person cannot even ask specific questions nor point out specific discrepencies. I mentioned the political reasons for this, I'm fairly confident they are correct. But I'm not even interested in discussing the evidence right now -that's not my point. My point is that the lie about the gas has now become a method against Israel for Muslims and others to reject the holocaust entirely - to throw the baby out with the bathwater, so to speak. That is my actual issue.
