Really? Censorship? And here in the US, people are trying to circumvent censorship too. So what? Doesn't mean we are going to side with china over the US. Also, there have been articles of china's demise for decades now. If you enjoy cringe, look up gordon chang and read some of his stuff.
But I agree with you about nobody wanting to be kept under anyone's heel. Do you know any chinese history? Do you know whose heel's they think they've been under for 200 years? The west's heel. Nationalism and economic growth is how the chinese government maintains power and I don't see that changing anytime soon.
As for the "concentration camps", I'm guessing the support depends on how it is framed. If the chinese government frames it as punishing separatist terrorists, I'm betting it will have as much support as japanese internment had in the US.
Also, the authoritarian communist party is their government whether you like it or not. Considering the economic growth that china has experienced, I'm betting the party and the government has enormous support amongst the population. And in any confrontation with a foreign government, the people almost always rally around their government - authoritarian or not.
Finally, "some" in china might want their government to "bend to the sanctions", but I'm guessing the vast majority of chinese don't. Also, historically, governments tend to fall when they appear weak, especially in relation to a foreign power. Also, you are conveniently ignoring the fact that there are "some" in the US who think we should "bend to their sanctions".
If you think that chinese people are going to side with a foreign government against their own ( authoritarian or not ), then you really don't know history or human nature.
