Some good comments on the "Reciprocation as the Basis of Rights" post

A few weeks ago I posted some lengthy, but well informed and intelligent comments on reciprocation as the basis of rights by a reader, Carol. An anonymous poster has left some comments in response to Carol's that I think are worth reading in hopes of fostering a discussion of what I think is the "where the rubber meets the road" area of the AR debate. That post is a few weeks dated, and is no longer on the front page, but it, along with the new comments and my response, can be accessed here.
