>Presuming that you are aware of these occurrences, do you agree with your government's positions and actions, and - if not - what actions, if any, do you take to make it clear your opposition?

I'm not from China and I disagree with the action of the China's government you listed above. However I wonder why this kind of opinion (aka the Chinese should be responsible for their government) is not commonly held against the USA?

The USA had invaded countries based on false pretext, toppling legitimate governments, and supported dictators all around the world. Why then, this "the Chinese are responsible for their authoritarian government" argument was not commonly held against the citizens of the USA, who supposedly live in democracy and therefore better equipped to actually change the situation?
