I quickly realized that there are two main kinds of diversity—demographic and moral. ... Once you make this distinction, you see that nobody can coherently even want moral diversity. If you are pro-choice on the issue of abortion, would you prefer that there be a wide variety of opinions and no dominant one? Or would you prefer that everyone agree with you and the laws of the land reflect that agreement? If you prefer diversity on an issue, the issue is not a moral issue for you; it is a matter of personal taste.
