Not a black-or-white (no pun intended) issue, unfortunately.

It is a fact that some (but not all) minority members attend schools that are, to put it mildly, well below average. These people need, and deserve, additional assistance to get into good colleges. IMHO, this should be in the form of a tutoring program or a probationary admission, rather than the "regular" admission of an academically unprepared student who is doomed to fail.

On the other hand, there are a lot of school systems that are fully integrated, in the best possible sense of the word, and minority students from these schools really should be able to compete with their peers. Is priority admission fair to the non-minority (oh, hell, let's just say white male) student who has worked his buns off in high school only to be denied admission to the university of his choice because it was necessary to make space for a less-well-prepared minority group member from his own school!
