The reason for the furor is because he's a highly visible, influential, and outspoken moron who once again said something that had wise folks from all political leanings cringing.
You mean just like Michael Moore and Medea Benjamin? My assertion stands. The media is trying to cover its tracks. It got caught making a celebrity out of another radical left-wing nutcase. Unfortunately for him, Robertson chose just that moment to pop up and remind us that radical nutcases come in all flavors. He provided the media with the cover they were looking for.
Outside of right-wing political circles (you know — where moderates, progressives, and average Americans fed up with the Iraq War reside) most recognize Sheehan as a mother distraught over the death of her son.
Sorry, no sale. The distraught mother gimmick lost its sheen when she started regurgitating trite, leftist agit-prop. Outside of left-wing political circles, Sheehan is seen as what she is: An unbalanced woman who has been manipulated by soul-less political hacks and seems very happy to be manipulated. Michael Moore says it and it comes out of her mouth. Everyday Americans are just as fed up with the shrill howling of the left as they are with the neo-con excuses.
