@Richard @c00p also, I watched that 4 hour documentary you linked elsewhere, and also the same guy's documentary on Auschwitz.
There are some fallacies in how/what is presented, but I'd agree that, given the lack of hard evidence, Treblinka, Sobibor, and Belzec were likely traditional concentration camps (in the same way that the US "relocation centers" were concentration camps.) and likely not "death camps".
None of the above should be misconstrued as "support": https://noauthority.social/@eriner/112418123430760958
