When Saletan says that "And then there are the self-imposed restrictions of each doctor. That third layer is the main reason why very late-term abortion providers such as Tiller are so rare."

He's ignoring the fact that a significant number of physicians and clinics are perfectly aware that there are pro-lifers out there who will bomb, harass, shoot, threaten and kill them if they do things with which these people disagree.

In fact, pro-lifers have fired guns into the these physicians' homes, fired guns in their churches, planted nail bombs, mounted judicial witch hunts, attempted suicide bombings with gasoline-laden cars, and so on. Until the pro-life movement ceases to produce terrorists, any claim that physicians choose not to do some abortions because they balk at the procedures on moral grounds is about as valid as claiming that American tourists don't visit Afghanistan because they don't like the towels in the hotels.

You don't have to believe something's wrong to want to avoid having your family's address listed under the category "baby-killer" on some website somewhere.
