It’s really frustrating, I was talking to someone about how successful China has been in de-radicalization of reactionaries. But they responded to this by saying they’re only successful because, and I quote “put them all in concentration camps and killed them”

Has anyone here been successful in deprogramming people about this topic? If so any good sources I can use to dissuade them? I tried telling them that the UN report, if you read it, just says that there’s concerns about abuse by internment offcials, and there’s no evidence of genocide. But when I say this they just dismiss it as if the UN is controlled by the PRC. It’s like a religion to liberals to believe anything bad about China and can get really frustrating.
