Your do a great disservice to the tens-of-thousands of victims of the communist states. I spent a lot of time in these places, looking at mugshots and intake forms and reading about what happened to them.
What do you think when you hear about a fascist antisemite standing in front of a pile of children’s shoes in a Holocaust museum saying “it didn’t happen”? Because that’s what I think about you right now.
And I never said concentration camps (edit: although these museums do tell the stories of the tens-of-thousands “deported” to camps in Siberia and other places), I was taking about buildings used for the imprisonment, torture, and murder of mostly political prisoners, but also others that upset the Nazis/communists in some way. Here is one example of many. https://www.terrorhaza.hu/en
I am not conflating Nazis and communists. I am comparing you to a Holocaust denier because of your conspiracy theories about the existence of these places established to educate people about the well documented atrocities of the communist states. I didn’t say they were as bad as the Nazis overall, I pointed out they happily used the cramped cells, torture implements, and kill rooms left behind.
It is very much not the exception in communism. I have been to almost every former Warsaw pact country and a few countries that were part of the USSR and these museums are universal.
