It's well established fact that Germans continued the use of chemical weapons in WW2, including on prisoners of war like captured Soviets. Zyklon B's deadly compenent is hydrogen cyanide. This does not disperse so quickly that le wooden doors mean it could not have killed people. In soviet captured camps, they did lie by omission about rebuilding parts, until it was found out later. Soviets also lied about things like shrunken heads and skin lampshades which were accepted even nearer the time to be debunked fabrications. But krauts no doubt committed warcrimes, no doubt sometimes using chemical agents, and it is NOT far fetched that graves would be dug up before fleeing to cover what looks le bad. Overall, there is good reason for uncertainty as to the death toll, methods of killing and disposal, and ultimately the Soviets were just as bad. We will NEVER know the full truth because of all the propaganda and misinformation of the time. Ultimately do not give a shit if it was 200,000 jews killed all over Europe, or 6 million. Much more bother by the roughly 1.6 million, mainly young, working class British lads killed in our involvement in both world wars. Fuck kikes. Fuck krauts. Fuck that cursed continent. Fuck hohols. Fuck subhuman asiatic Russoids. Fuck everyone not an Anglo Englishman. Okay, thank you.
