It numerically makes no sense, it logically makes no sense, in so many ways nothing about the alleged holocaust makes any sense at all. The numbers don't add up, there's no possible way any sizeable number of people could have been gassed and cremated, if the Jews were shot or buried alive there's literally no evidence of that anywhere, there's no ash concentrations to account for 15,000 TONS of ash, there's no major soil disturbances around the camps, and this doesn't even get into the logic of "WHY"
WHY are there swimming pools, fire stations, hospitals, legal offices, post offices at a death camp?
Why would a nation with the goal of extermination of a populace dedicate literally any resources whatsoever to the maintenance of said populace?
If the goal was extermination, why would the Germans do anything save for build a large hole in the ground and push them all into it? After all this country was the pinnacle of engineering prowess at the time, I find it impossible to believe that it would have really taken Germans years worth of inefficiently burning bodies for no discernible reason, using gas that remains toxic for a full 24 hrs after exposure, again for no reason, instead of just shoving all the Jews into a giant hole in the ground and covering it up.
This again comes in the midst of many, many admissions from "holocaust survivors" who admit that their stories were lies, revelation of things like the fabrication of Anne Frank's diary -- Elie Wiesel's "Night" novel, major holocaust speakers coming out and saying they lied because "in their mind it was real".
Nobody is denying that concentration camps existed. If you recall the USA did similar to the Japanese in WW2, the only difference being that the USA was not under heavy carpet bombing air siege for the duration of their participation in the war, and therefore could manage to FEED their captives.
There is no evidence of any mass Jewish extermination at all
