Well, since I'm a left-wing person myself, what Lilly says makes sense to me. Also I think that his data seems sound. Clearly, though, I'm not unbiased here. And I'm not saying that people should not be responsible for their own choices.
As for the Palin thread, yes, I have decided to stay out of it. I could inject a lot of emotion, but no useful information. No one benefits from that. But it has been informative and interesting to read what the rest of you have said.
