From his confession, quote... Those who call themselves pro-life and who claim that abortion is murder and that those who use force to prevent it are just as morally reprehensible as the abortionists For these, I have nothing to say other than that you are liars, hypocrites, and cowards. There's no more fundamental duty for a moral citizen than to protect the innocent from assault. That is inherent in the values of all higher civilizations. You have the right, the responsibility, and the duty to come to the defense of the innocent when the innocent are under assault. Would you protect your children from the clutches of a murderer? Would you protect your neighbors' children if they were under assault? If you answered yes to both of these, then you must support the use of force as justified in attempting to prevent the murder that is abortion. That's very straightforward. Sure. Direct. I mean, they're all a bunch of hypocrites and cowards. He's arguing that it is a moral necessity to support violence in the service of opposing abortion.
