All of the talk about polygamy in here has prompted a lot of email about and from Mormons. I recalled that I had actually written something about Mormons before, so I went and looked it up. This column doesn’t mention gay marriage at all, but I still think it’s relevant. My basic point was that Americans have religious pluralism but moral consensus, historically speaking. I think that’s less true today. But I do think it’s worth noting that this debate on numbers-versus-sex (see yesterday’s posts) falls squarely in this American tradition. Gay marriage proponents claim they want to join the moral consensus not live outside of it.
