I couldn't agree more. It's also quite insulting then they think their opinions are of some universal truth even when presented with evidence. I have seen Americans with superiority complex when faced with an unfamiliar surrounding. They seems to go around talking about how everyone is doing everything wrong and their own culture is without fault. The majority of Europeans I have met seem a lot more willing to accept other cultures. Europeans often have to learn a second language that isn't English and frequently travel to neighboring countries. I think the simple understanding that there is a world outside theirs from a young age makes a world of difference is separating their perceived negative emotions and facts.
I am going to get serverely down-voted for this, but look at seanmcdirmid as an example. He almost exclusively posts on Chinese articles on Hacker News. His past comments always paints an entire country as negative. He likes to state his opinions are facts and when saying something mildly racist, he ends is posts with "my wife is chinese". Like that makes any difference, its the equivalent of those saying they aren't racist cause their neighbors are black. I have no doubt his experience in China has largely been negative, but with his attitude I am not surprised.
