Holocaust callout

Hey /politics/, roughly a little over a week ago, I got into a trainwreck of a debate on /n/ regarding the holocaust, and that one archive- containing millions of documents totaling to 16 miles long- was brought up. Which had information on all the various victims of the holocaust. Then, someone brought up an email conversation they had with one of the archivists, asking if there were forensic documents indicating if any of the victims were killed by zyklon-b, which the archivists replied with no.

They still haven't replied to me asking the same thing, but it dawned on me: why the fuck would the germans have autopsies of the people they killed?

I'm posting this because the same guy asked me to post it here, and /n/ is just too much of a shithole, so....

Ok you can spend all day arguing back and forth wether it really happened or not...but let me say this my great-grand father left poland just befour the war. He left his entire family behind bringing only his wife and two young daughters. The war breaks out and the entire family that stayed is never heard from again. Where did they go? What happened? And why would all thoes people who came out alive lie? People from diffrent countries and backgrounds and even in seprate camps all had the same stories of horror. Explaign that...they dont even speak the same language yet told the same stories.
