I'm not sure how common it is in this day and age that any public university is going to have a policy that let's it be nearly all white. But you keep bringing up this hypothetical, rather unlikely, worst case scenario in order to justify your support of affirmative action across the board. I'm talking about public policy in the over all picture. And diversity of a student body should not be used as an excuse to let certain women and/or minorities, who are less qualified, go ahead of those whites/men who are more qualified. It should be based on qualification alone. Not on race or gender.
Laws are there to ensure that worst case scenarios won't happen. As for your assumption that someone less qualified would get ahead of a white male, I refer you to Frank's post.
Diversity is not the excuse. It's normal to assume there are bright talents among minorities and among women who would be discriminated against if not for affirmative action.
