In a paranoid totalitarian ethno-state I don't think there's any real correction for minorities, only oppression. And the facilities are used accordingly.

I’m not talking about Chinese youth correctional facilities - no idea if they exist, I’d guess they do - but about the western ones. You get there for a couple of months, against your will, and you’ll be taught things like language, how to interact with the rest of society, and how you can fight stuff religious fundamentalists are forcing you to do. State propaganda calling that a concentration camp looks rather silly.
