A rule to live by: WWHO: Did you read the story about Harvard setting aside gym hours for Muslim women only? Now, a principled administrator would have looked at how other religions on campus were treated and would have concluded that it is not fair to give preferential treatment to one religion. You might respond that the ethics of a liberal require that we favor the little guys, and Islam is a small group in America. My answer is that Pentecostals are a small group too, but we can imagine Harvard's response to a request for special treatement from them.
I think I might have the answer to crack the mystery of elite ethics. Really, it's so simple even a toddler could grasp it. It could be called the "WWHO rule" (pronounced "who"). WWHO means What Would Hitler Oppose. If Hitler is against it, it must be the right way to go. If a Muslim girl comes to you and asks for the gym several hours a week all for herself, well obviously Der Fuhrer would snarl a "NO!" at her, so it must be a good policy.
The rule really applies to everything. Racial issues are obvious: mass non-white immigration is a must since that would drive the NSDAP nuts. And social issues are clear too: Gay marriage must be right because Herr Hitler loathed homosexuality (except for when he was a male prostitute in Vienna, they say). But the rule even works in the area of taste. Jazz is the greatest music ever since the Nazis hated it. Even science must conform to this principle: biological sources of behavior must be false since You-Know-Who would like that idea.
The Golden Rule or the old "What Would Jesus Do" might work for the hicks, but WWHO is the only way to go for the truly enlightened.
