Just want to weigh in on this one as a current Uni student.
but first @Frank: you're right, there is no such thing as reverse-racism, as reverse-racism is just racism and separating the issue into two concepts is just silly.
Now onto this issue of affirmative action, before arriving at Uni, I would have agreed with the notion that socioeconomic factors are more a more accurate way of dividing and judging a student body than race. However, now through making the friends I have made and interacting with the students at my school I have come to realize that the racism in this nation is so deeply rooted that even people from identical socioeconomic and geographical locations who are of different races still have ENTIRELY different life experiences. I wasn't sure how I felt about affirmative action before my arrival, but I am now a full supporter. In practice today, judging people by their race will indeed yield the greatest diversity in a student body. This is unfortunate, but it's true as far as I have seen.
Secondly, I don't think any of you understand exactly how colleges and universities choose their students. From the start, they have VERY specific brackets they are trying to fill. These brackets are based on geography, annual income, type of high school attended, legacy, skill set, and when they can be, race.
finally @Tolstoy: Asian race superiority? really? I recall reading a Time? (maybe NatGeo, or even Scientific American) article a few years back that attributed the concept of "Asians have higher IQ", an argument I'm assuming your "Asian racial superiority" factors into, if not predicates, to a harder work ethic in general. They weren't superior genetically but achieved more with what they were given. You could still attribute that to race, but its sounds like social construct to me.
