I suggest you look up what most concentration camps were like. Auschwitz was an exception even by the standards of concentration camps and is nowadays usually called “extermination camp” for that reason.
That doesn’t mean that the other camps weren’t horrible, they were, but they were also awfully comparable to a lot of things that happen in the US prison system.
I see erininthemorning.com and the title and I upvote and don’t read beyond that, because I know it’s just going to be depressing (and thankfully doesn’t directly affect me)…
