So because Chinese rulers have oppressed and mistreated their people for so long that their methods have become ingrained in the national psyche, it's somehow more OK?
George Orwell predicted that "If you want a vision of the future, imagine a boot stamping on a human face - forever". He thought he was making a dystopian prediction, a warning of sorts, but he could've just as easily called it a history lesson about China.
Sure, many other places, most places in fact, have horrible histories, with evil rulers vastly outnumbering the even somewhat good ones, but China is unique in that it's been all about oppressing and abusing the population as heavily as possible, without pause, ever since the first emperors gave the country its foreign name.
A non-stop tradition of oppression doesn't somehow make new oppression less bad.
NOTE: Nothing against the Chinese culture or people. I'm extremely fond of lots of Chinese things, not in the least Chinese humor for which I have a particularly soft spot. I love working with Chinese people, I love meeting Chinese people. It makes me sad that such a wonderful place and a wonderful culture can also have such a horrible tradition of oppression.
