You're jumping to conclusions, PA. I actually like Chinese people a lot. I'm married to a wonderful woman who is half-Chinese and we have a lot of Chinese friends, but unlike you, I can't say that I've noticed they are particularly patriotic, to say the least -- unless it's patriotic toward China -- just opportunistic (which, btw, I don't have a problem with). Many of them are thoroughly brainwashed and very touchy about any criticism of that dictatorship. They're here to make a buck and get an education at the best universities in the world and then go back and help their country. I've heard this reasoning from them over and over and over again. And let's not forget, China does require them to return after their education. We should be much more cautious in allowing foreigners to come here to study, imo (incl. Canadians).
And many Americans who become good friends with or enter into business relationships with such non assimilated PRC expats often become brainwashed themselves, and end up being the worst sort - Americans who are Beijing bootlickers. Such things have happened in the past. Vis a vis Nazi Germany there were many apologists. Same deal with the USSR (witness Armand Hammer as a particularly amazing example...).
