回复：开放自己!

"来美国三年多了, 看到了美国的强大一面, 体会了美国的选举,"

I doubt you 体会了 any thing significant about American election.

"我只是看到有些人出国后变得越来越狭隘, 金钱意识占超主导地位"

From my observation, the people in China has turned a lot more "money" oriented in the last 10 years than those Chinese in the US.

"华人在外可能会遇到歧视和欺辱, 但就我个人认为这与有些华人不爱国, 自私, 不愿做社区义务服务, 不愿为灾区捐款, 不把社会的责任作为自己的责任, 封闭自己, 不接受美国的文化有最直接的关系."

That is right. But I am surprised that they came out of your mouth. Maybe you did not realize what you are saying here. Do you realize "不愿做社区义务服务, 不愿为灾区捐款, 不把社会的责任作为自己的责任" is a Chinese culture? What you are saying is they should abandon Chinese culture (at least this part) and follow the American way.

"因为我们的特征性的黑头发, 黄皮肤. 不要认为你受的苦难只是第一代移民才会有的, 你的下一代就不会再体会到了."

You are a racist.

"我认为如果中国人不爱自己的国家, 不把你现在生活其中的社会的责任作为自己的一个义务, 继续过着一种与世隔绝的生活, 这种歧视会越来越重,甚至可以想象有那麽一天就会有反华游行, 反华议案, 反华暴力, 可以想象你们的后代们将经受更多的苦难."

Which country is "自己的国家"? US, or Mainland, or Taiwan? I can hardly perceive that if all those Chinese who became US citizens align themselves more with the self-declared government in Mainland would help avoiding being discriminated. It should have the opposite effect.

You are confused of loving a country or loving its government: "我真的为李安而感动, 为他每次用中文对祖国, 对祖国人民的祝愿而兴奋和自豪. 他没有没有长在中国, 却一再重申自己是中国人. 虽然中国官方禁止'brokeback mountain'在中国公映, 可能他有些失望,". Did you feel the same "感动" when another Chinese got a MUCH more significant prize a few years ago? I did. I bet you did not.
