In case it hasn't bubbled up to you yet, head over to Gene Stone's post (many amusing comments) on a perfect squelch of a wingnutter.
Maryland's legislature was considering a crazed, extreme-right anti-gay/-SSM/-civil unions amendment. On its way to defeat, it found a defender in the loony state senator. She stood up to attack a rational colleague, screaming, "Mr. Raskin, my Bible says marriage is only between a man and a woman. What do you have to say about that?"
He had the perfect answer.
