I attended a law school well known for "diversity." Our classes were filled with people who were diverse by race, sex, and geographic origin, most of whom thought exactly alike. I was one of the few persons, and sometimes the only person, who supplied diversity in class discussion, even though I was on paper the least diverse person ever, being a white male non-athlete from the Washington suburbs.
Then again, as usual, conservatives are in no hurry to lead by example. Indeed, when they make up the majority, they forget all of their fine words about viewpoint diversity. Free Republic quickly banned me for expressing an opinion that was by their standards politically incorrect. The thread topic was - you guessed it - the threat to viewpoint diversity by those nasty liberals.
