Yes, yes, yes, the Chinese army crushed a protest at Tiananmen Square in 1989. I believe this to be a bad thing. Yes, they censor it like crazy.
I'm just tired of seeing it used as a "gotcha", when in fact many Western governments have done similarly egregious things and then covered them up.
For example, how the US government just murdered a continent-load of people to take their land, and how they teach the colonisation of America as a family friendly children's tale.
