You’ve asked three important questions, the first of which concerns the right to speak about abortion. Legally speaking, everyone has a right to free speech, including speech about abortion. Morally speaking, every person of good will has the right and obligation to speak out in defense of the defenseless and in favor of a just social order. The question “What right do you, a man, have to make a case against abortion?” seems to presuppose that abortion is simply and solely about women, but this is a false supposition. The majority of abortionists are men — more men than women describe themselves as “pro-choice” — and in the United States, men pay for abortions with their tax dollars. Aside from these considerations, every abortion involves the pregnant woman, the expectant father, the one who is aborted, and the society that allows it.
Secondly, although abortion is currently legal in the United States, it is also currently illegal to force any doctor to perform an abortion. The Church amendment, passed shortly after Roe v. Wade, protects pro-life doctors and institutions from being forced to carry out abortions. Doctors and nurses, as mentioned, have no legal obligation to provide access to abortion, nor do they have a moral obligation. Indeed, the Hippocratic Oath says, “I will not give to a woman an abortive remedy.” A doctor’s proper role is to heal patients and promote health, not to injure and destroy human life. I develop this case extensively in my book as well as elsewhere online.
