As Chinese, I never hate Americans. I study in Florida. I get along well with my teacher and classmates. They all like me very much. I don't know when the saying "Chinese hate Americans" have started. So our situation is the same. I only want to say, no matter Chinese or American, no matter who you are, when facing death, we are the same. I know you are still alive, and maybe your feeling is not so deep. However, please imagine that if there were your relatives and friends in the explosion, will you still want to make jokes? Maybe you see the video just for fun. I just don't understand why you could gloat for this.
