I wouldn't say that the comments are necessarily pro-China though, but rather just explaining that it is a different culture and things are done in a different way.
I do think it's a bullshit cop out though. I think that it's ignorant at best and racist at worst when people make comments here along the lines of "Chinese people like authoritarian societies and couldn't function in a democracy", usually justified by saying that China has been an authoritarian society since day 0. Europe, until recently, was a continent ruled by autocrats (whether in the form of kings, presidents, or emperors).
There are plenty of Chinese democracy activists, and I'm yet to meet a Chinese immigrant who has any love for the CCP and the Chinese government.
