No biggie. Banning gay marriage is an undue gov't intrustion into the private realm, anyways. If two gays want to get married, it is no skin off my nose..
I guess if you ever have children you won't mind when they're taught in school that if they've ever had a "gay" thought that they ARE "gay", can't change, and the nice "gay" counsellor will assist them in "coming out" and learning the ropes of "gay" sex.
