I once attended a talk given by Richard Pipes. During the Q&A afterward, someone spent about five minutes going on a rant about how private property was immoral and that all things belong to God, so it's even sinful to say that my yard is mine and not accessible to any one of God's creatures who wants to use it.
Pipes sat there patiently listening to this member of the audience have his say and then ask how he responds to this argument. Pipes politely and respectfully answered the questioner (I thought beautifully and using real world examples of the human atrocities that resulted under political systems where property was collectively owned.), not once raising his voice or getting defensive. It was a lesson in how a master responds to criticism of his work.
I often get frustrated listening to Jon Stewart for his one-sided remarks and sometime petty attacks, but I give him credit for the way he handled Bill O'Reilly in this clip. It reminds me of Richard Pipes and offers a great lesson on listening and mirroring back what your critic is arguing as a way of making your own point.
