Gulag just means prison in Russian. I don't know what they call prisons in China, but its not gulag. The prison system refered to as "the Gulag" in the west only existed for like 20 years or so. Less people were imprisioned in that system than at any time under Czarist russia, and far less than in the US now.

Just because it has a foreign name doesn't make it anything other than just a prison. I know you're an anarchist and for prison abolition, which is cool. But don't act like there are some kind of extra bad prisons in AES
