Andrew Sullivan points to the courageous story of a young man who received a purple heart in Iraq and now wants to stay in the military. The catch? He's gay, and his admission comes as a direct violation to don't ask don't tell.
Conservative groups go insane over these sorts of things, but it is beyond dispute that "don't ask don't tell" is hurting the military badly in the war on terror. Conservative opposition to ending "don't ask don't tell" is frankly unpatriotic, and they should be ashamed to say "you cannot serve your country because we fear you."
As Conservative Godfather Barry Goldwater once put it: "It shouldn't matter whether you're gay or straight. All that matters is whether or not you can shoot straight."
