I don’t usually publicize my NRO articles in The Corner, but today is different. “The Libertarian Question,” is definitely one of my more ambitious pieces. Taking off from the controversy over Senator Rick Santorum’s comments, I try to explain our taboos on incest, homosexuality, and adultery. I also try to show what these taboos have to do with each other, and with proposals to legalize same-sex marriage. In the course of the article, I attempt to meet the chief libertarian arguments in favor of gay marriage. My hope is that this piece will help to take our ongoing debates over gay marriage to a new level.
