Wow, look at the amount of condescension! Only Indian and Chinese students need to broaden their horizons, not White students, right? Asians need to understand the difference between cultures, Whites being superior of course don't need to understand anything like that! Why are you assuming that all Indian and Chinese students behave exactly alike? Do you think diversity of behavior is to be found among Caucasians only?

You also didn't consider the issue of latent racism at all. A lot of times fresh off the boat Asian students get rebuffed by Whites if they try to develop contact. Often it takes the form of making negative comments about their home countries - how poor/regressive/authoritarian they are. Nobody likes getting badmouthed. This is one of the reasons they form so called cliques.

Sorry to call you out, but I'm sickened by your racism.
