If it were true that gays can't control their sexual behavior, then not only shouldn't they be in the military, they shouldn't be allowed out of the house without restraints.
But that's the absurdity of this whole rigged-up tricked-out argument. It's the "bigoted" "cultural conservatives" who stand alone in saying that gays have the same dignity, rights, and responsibilities as any other beings who possess intellect and will.
Controversial? At the University level, apparently.
Although a few fall short, I would refer to Catholic priest and nuns to buttress your argument.
