I've lived in China, I still go China every year. Simply put, you don't know what you're talking about.
Daily life in most of China does not feel repressive for most people. There is, if anything, less police presence than in the US. Joking about reeducation camps because you know your post will be downvoted is just playing the victim to preempt contradiction.
The specific case of Xinjiang is worrying because after years of increased liberalization, it's a return of nationalist politics. That said, they took a leaf from Western governments there: specifically repressing Muslims does get into headlines, but hasn't brought much actual condemnation from West, particularly, not from the USA's Muslim-ban president.
