<p>As far as I know the only universities which have explicitly stated that they do not use race are the publics of Michigan and California, and as far as I know there have been no proven cases of these colleges being definitively caught practicing racial preferences. The two theoretical examples (or something else along those lines) that I already stated are the only ways that a university can be without a doubt caught practicing racial preferences, but a large disparity in admittance rates and stats can cast doubt on a university, to say the least, though I have no idea whether it is enough for a lawsuit, if that's what you mean by proof. For example, from the Daily Bruin, speaking about UCLA: "In fall 2007, black applicants’ SAT scores were on average 293 points lower than those of white and Asian students, and Latino applicants’ scores came up 249 points short." <a href="http://www.discriminations.us/2007/05/the_measure_of_preference_at_u.html%5B/url%5D">http://www.discriminations.us/2007/05/the_measure_of_preference_at_u.html</a> (also has a lot more on AA and the UCs, but I didn't want huge walls of text)</p>
<p>"-You clearly think racial diversity is not "pertinent" to college life, so I want to know which things you believe are in fact relevant."</p>
<p>No, I don't. Academic record, things that may have affected academic performance, ECs, things someone can contribute to a college outside of just what they look like, crapload of other things that I probably missed.</p>
