Dreher thinks it was a petty move, which it was. Michael Kinsley is right:
The more times [Joe Wilson] is required to write "I will not call the President a liar" on a special blackboard set up in the well of the House, the bigger hero he will become to a large chunk of the population. And, of course, forcing him to grovel will not help to convince him or his supporters that the president is not a liar.
