He's differentiating between prejudice and discrimination in his post. Universities discriminate against stupid people all the time, that's how their admissions work. What's not a good metric to discriminate upon, is race, because it doesn't offer insight into how successful the student may or may not be. Those sorts of qualities (race, gender) are not things to discriminate upon because doing so would be prejudice; which by definition is not an effective method of discrimination.
I think you misunderstood my post. Your question is exactly the problem I addressed. Universities HAVE to discriminate; they cannot accept every applicant. The question is how are they doing it, is it a good way, and is there a better way.
You discriminate every time you purchase one product over another, take one job over another, live in one area over another, befriend one person over another, etc. We all do. The key to doing it well is clear, analytical judgement about such decisions. Personally, I haven't seen much of that in University admissions at any school.
I am ok with private businesses or individuals going about their own business with whatever racist, homophobic, sexist policies. I don't care. I simply won't visit them or pay for their service. I read my fair share of Rothbard, Friedman and Block. Discrimination in the sense of making choice so long as the choice doesn't violate the rights of other is ok, even if it is morally despicable.
This issue of universities is completely different. Even private universities get public funding. Universities are inexplicably tied to tax payers including Asians. This is where I see the problem. Either remove public funding from universities operating admission based on racism or stop having a racist admission standard.
