Diversity and attempts to diversify are stupid.
95% of these diverse students along with 95% of the others (whoever they are) don't care about learning about other subcultures.
Have you ever noticed how minorities seek each other out. White people do it when they are the minority too. I am not saying that this is a good thing, but it is the truth. Just ignore diversity and bring in deserving students and let them do whatever the hell they want to do.
One of the most important aspects of my undergraduate experience was the diversity of people I got to know. I met citizens of difference countries and Americans from all over the country, each with a different experience. I now have friends who live all over the world who are white, black, indian, asian, puerto rican, spanish, swiss, japanese, straight, gay, rich, poor, musicians, teachers, humanitarians, CEOs, and yes I even met a conservative. That was a very valuable part of my undergraduate education, and I am glad that the admissions and financial aid people at my college took the time to get such a broad spectrum of people. Maybe my undergraduate experience was unique, though.
