It's good that folks like Sheehan are transcending anger, because although anger can provide the energy to affect change, it is a dangerous thing when uncoralled.
But like Sheehan anger can be transformed into something better.
And the right is clearly unsettled with Sheehan, because she's the real deal. She's someone who sacrificed her child - the righties I see smearing her have never really understood sacrifice, have never understood the cost of freedom has to be paid by acting freely, and most importantly, have never understood that anger and resentment aren't meant to be fed with more anger and resentment, but can only be sated by compassionate action.
She's not simply aping MLK or Gandhi here in calling Bush and the righties to accountability- and even if she was, the call to accountability would still be sincere, and would still demand a response.
And responsibility is all she's asking. It's all anyone ought to ask of those who are employed by us, such as Bush.
