I understand why you would feel that way. In fact if I were grown up in the US or the west, I would reply the same thing.

The thing that many westerners like you do not understand, is that it's not simply a fight between China and the free world, there are other parties that deliberately paint China black and the free world would gladly welcome them as their allies.

So when there is overwhelming evidence that China is bad, combined by the good investigative journalism and the rumors created by the 3rd parties, it's hard to distinguish one from another.

Now, there are plenty of people who disagree with me, some of them are good people, they present evidence and facts, and I do not try to argue my way out. But at the same time I had to recognize that there are people who pretend to be genuinely interested in freedom of speech but with the hidden agenda, which I had to disagree with.

The problem here is that the two are often mixed together, in news articles and on Wikipedia, hence it would appear that people like me are lunatic and having the mentality you described above.
