Before I head out of town on vacation, I’ll note that I’ll be taking part in a discussion of same-sex marriage on Tuesday, Sept. 7, at Northwestern law school. The event is jointly sponsored by the law school chapters of the Federalist Society and the American Constitution Society and will begin at noon. The other confirmed participants so far are philosopher Martha Nussbaum and Camilla Taylor (an attorney with Lambda Legal). (There’s not yet an online link for the event.)
