No it is a simple matter of evidence. For example, it is easy to confirm cyanide it the gas chambers .it woulf be in the walls and paint for 300 years. That exists, i assume?
PS I have seen clear and convincing evidence so that I think people who deny mass extermination by the SS happened must be at least a little cray-cray.
The deniers raise questions like:
Why go to the trouble of tattooing people you plan to take from directly from the train off-loading to the gas chambers,
Zyklon B was used for delousing, there wasn’t enough Prussian blue staining to evidence the use claimed,
Why were Zyklon canisters found at camps without chambers,
Why were there no holes found in the roofs of the gas chambers,
Why would they use Zyklon, an insecticide when they had chlorine and mustard gas from the first war,
If so many were killed, why are there so many survivors,
and other questions that might make you stop and think if you are so inclined or predisposed.
I didn’t mean to be dismissive, we were all noobs at one time. Rock on Garth.
