The "Central Question" about Marriage

Here, at Public Discourse, is the latest (I think!) installment in the ongoing conversation between George, Anderson, and Girgis (on the one hand) and their interlocutors / critics (on the other) about the meaning of marriage, and the implications of that meaning for law and policy. 

I propose that Robby put up the next few installments of the conversation exclusively here, at MOJ, so we can reap the huge benefits of the web-traffic attending it.  (Ed.:  You do realize, Rick, that MOJ makes no money, right?).
