I thought Olbermann's special comment was one of the best I've heard on the topic. I was particularly enamored of this:
If you voted for this Proposition or support those who did or the sentiment they expressed, I have some questions, because, truly, I do not understand. Why does this matter to you? What is it to you? In a time of impermanence and fly-by-night relationships, these people over here want the same chance at permanence and happiness that is your option. They don't want to deny you yours. They don't want to take anything away from you. They want what you want—a chance to be a little less alone in the world.
Olbermann, Countdown What's so wrong about that?
