I concur with this. I once saw an American student, studying in Europe. A European student was critisizing her country's government. The conversation did not go well, she eventually cried out in tears. That is when I realized Americans care deeply about their country. Americans complain among themselves about their government all the time but it is a different matter if an outsider complains about your government. Probably the same thing is happening when you talk to Chinese students.
