To qualify my yes vote: as the PRIMARY factor? No it should not come ahead of qualifications. As a SECONDARY factor, I don't have a problem with it.
For example: You have 10 remaining spots and 50 applicants who all have similar qualifications. I don't have a problem with taking 7 black kids in an effort to make your student body more diverse. Or even if you fill all of them with minorities who are similarly qualified.
The problem is, we don't know how they are qualified. Is a white kid with a B average and horrible writing skills more qualified than a black kid with a C average who expresses himself in words rather well? Is a middle class black kid from the 'burbs who cruised through without trying more qualified than a white kid who had to scrape and fight his way through?
