Reading and thinking about Terri Schiavo's case has brought me a strange thought. Liberals favor a Darwinian bioethics; conservatives favor a Darwinian economics. Each vocally decries the other's Darwinism and insists on the moral imperative to protect the weak -- as defined economically by liberals and biologically by conservatives.
It has also occurred to me (now I'm going to piss everybody off) that the psychology of the extreme wings of Right to Life and Animal Rights is much the same. I am not making any statement here about the comparative value of a human fetus and an animal. That's a whole other subject. I am making an observation that taking on the role of Defender of the Helpless Innocent -- a role that justifies and purifies the expression of considerable rage -- holds much the same surreptitious satisfaction for those at both extremes.
OK, I'm ducking.
