I have no personal insight into Confucius Institute censorship, but the reason I wrote “nation states” rather than China was because I agree, this applies in all directions.
Confucian does not mean pro Communist and not pro CCP as some Commies have to learn it. I read in an anti China Magazin a reasoning for human right based on Confucian philosophy made on by Taiwanese philosophy phd student in Germany.
I guess these discussion won't happen in your mentioned Confucian learning events.
