We’ll leave aside the garden-variety hypocrisy of people who have suddenly discovered that dissent may not always be the highest form of patriotism. (And, to be fair, those who have suddenly rediscovered their right to peaceably assemble and demand redress of grievances)
Talk of death panels and crazy signs is, if polls are to be believed, a tiny fringe of the many Americans who do not like this health care plan much. It’s even, as far as I can tell, a small minority of the many Americans attending town hall meetings to harangue their congressmen. Democrats appear to think that blowing those people up into the totality of the movement will help them win the PR battle on healthcare. I suspect this will do more harm to the Democrats, and their ability to effectively deliver their message, than it will to the conservatives.
