I couldn't agree more with Jay's post. It should be an imperative for those who claim to be pro-life to understand the grounding behind our moral reasoning. Tiller's death not only brings difficult practical issues for our movement, more importantly it was an evil act that undermines and controverts the moral basis behind our claims.
The moral logic of the pro-life position is that human beings are intrinsically valuable. We don't obtain that value when we reach a certain point in development, or when we have certain capabilities. Likewise we do not lose value when we inevitably lose our capabilities or become ill. Our intrinsic value also does not depend on our behavior. It is clear that human beings have a tremendous ability to do evil and to perform outrageous actions against others.
This intrinsic value is what we ground the concept of human rights. Let me be clear; if human beings are not intrinsically valuable, then there is no pro-life argument. A vigilante murder of an abortion doctor undermines the very basis and grounding of our argument.
As we endure the inevitable media backlash that will result from this tragedy, we must continue to strive to understand the basic pro-life argument and to work to have others correctly understand the logic of our position. This murder will not only draw attention from the truth of our position, but actually undermine it. This act deserves our strongest condemnation.
