B is a loser, she is weak inside, that is why she behaves

like that. I was very weak when I just came to USA, I am ashamed of some of my behaviour at that time. Extreme poverty and extreme political insecurity have destroied many Chinese's diginity/confidence. You probably is too young to know all that history. When people are not secure in basic survival, asking for more is just not reasonable. I am not saying B has the right to do things like that, I am just saying you should understand why some Chinese sometimes behaves like B. If you can't see that, you are pretty shallow yourself. I assume you are from mainland China, you have the same kind of culture identity, another side of the same coin: intoralence, when you generalize B to all Chinese, particularly young generation of Chinese, you are doing racial discrimination. I am pretty sure you will discover that other ethnic groups have their own, maybe different problems.

If you are really a hero, as a Chinese, go back to China, do some changes, make your own mark. I will admire you for that.
