I think that should not give a license to stop discussion and criticism if you are from a different country. There is a pretty good understanding of political ideologies across the world about authoritarianism. We have seen the results of dictatorships and authoritarian governments and how they turned out. There is absolutely no reason to say that "It is different, it is a different perspective about governance". Absolutely, it is different and there is a universal understanding of what that difference is.
George Orwell accurately outlines what is going on in Kashgar and other regions in China. He outlined it decades ago.
If I were Chinese citizen, I would be the first one to question the government's actions. Except, that the Chinese people tried to protest in 1988 and it ended in a massacre.
I have been to China many times and I love the people there, culture, and how they live lives just like anyone else in the world. Criticism against the government and political ideology has nothing to do with "an attack against China". I know you're not saying that but I wanted to clarify.
