Anthony asserted that the parent's moral ability to initiate force on their children is affected by their duration in ability to do so. Anthony's last quote on the subject, I believe, serves as a fair summary (and Anthony, if you disagree, feel free to chime in right away):
"To the point I make about duration, I do not assert there is any positive license granted specifically by limited duration. Instead, I am trying to establish how parental initiation of force is incompatible and distinct from government because government is effectively unlimited in duration. In other words, to say 'parents can' does not imply 'governments can' because of the differing duration characteristic."
David, I open the floor to you to respond.
