Wilson was rude, but "precedented"

I posted earlier this week (here) about Joe Wilson's outburst during the Obama's healthcare homile, in sum, I thought his heckling was not cool even if his assertion was correct. But it appears that he may have gotten the wrong idea about how to conduct oneself during a presidential address from . . . (drumroll) . . . Democrats:



From this video, it is fair to conclude that Wilson's problem was that his rudeness wasn't lost in a sea of rudeness from his fellow party members.
