And they were in sealed gas chambers!
Imagine the luck of the Nazis that they miraculously managed to carry out thousands of gassings in massive outdoor rooms in polish winter with wooden doors and were able to remove the bodies instantly even though hydrogen cyanide stays lethal for so long afterwards!
Of course any intelligent person knows the holocaust is about as real as bigfoot or viruses etc.
another aspect of cyanide use that not one "survivor" account mentions are all the ancillary deaths among the guards who handled the gas or the inmates that handled the bodies. if the cyanide and the bodies were handled the way the "survivor" accounts claim, there would be thousands of dead guards and tens of thousands dead inmates.
nor are there any survivor accounts that mention the effects of a non-lethal dose of cyanide. nausea, headaches, fainting, mental impairment among those who handled the bodies of the gassed or somehow miraculously survived their gassing aren't mentioned at all.
nor are there any accounts of explosions at any of the gas/shower sites. there's reasons written in blood why regulatory agencies have strict rules regarding electricity/electrical equip in areas with explosive gasses. all of the pictures of the supposed gas chambers show what would be statistically catastrophic electrical practices if hydrogen cyanide would have been in regular use the way "survivor" accounts describe.
TFW my biggest holocaust redpill came from OSHA10/OSHA30 cert vids.
