The best way to deal with repugnance is to listen to it, articulate it, and incorporate it. It's part of morality, even when, as an argument for prohibition, it's overruled. The answer to conservatives who believe in one truth is not that there are no truths but that there are many, and this one, while important, isn't final. The result shouldn't be chaos. It should be structure.
That's what I told the liberals last night. And you know what? They listened, asked questions, challenged me, admitted uncertainties, told me some things I didn't know, and gave me new problems to think about. Everything was open for debate: agreement, disagreement, and doubt. As long as it stays that way, I'll be one of them. I think.
