>China is now prosperous and powerful without them.

If you feel so strongly that way, tell President Pooh Bear to stay out of the Taiwanese territory. They like their liberty and don't have to worry about social credit scores, being forcibly contained in their apartments for months at end over a nonsensical zero-Covid policy, or worrying that if they speak ill of their government, they'll be sent out to a PRC concentration camp. If you like your authoritarian daddy state, stay the fuck there. The free world doesn't want you.
