Eugene Volokh has an interesting post, with a link to an even more interesting (because longer) article of his on diversity, racial preferences, and religious preferences. He far too modestly minimizes the importance of his fascinating subject — what principle, for example, would accept the legitimacy of racial preferences but not of religious preferences as well?
One of the reasons I think this question is so important is that, er, I’ve written about it myself, here.
Well said!
