If you're gay and in the military:
Dan Choi, a West Point graduate and officer in the Army National Guard who is fluent in Arabic and who returned recently from Iraq, received notice today that the military is about to fire him. Why? Because he came out of the closet as a gay man on national television.
Ignorance begets ignorance. Ignorance of homosexuality will now make us more ignorant about the Arab world.
Meanwhile, as Matt points out, repealing DADT won't ever be convenient. There won't be any politically expedient about it. It's the sort of move you may well lose some votes over. At some point, Obama is going to have to honor liberal tradition, swallow hard, and throw the long ball. It's not suppose to be easy to do the right thing. That's why so many don't do it.
