The Pro-Life position believes that a) human life begins at conception, b) abortion is a sin, and c) the sin of abortion should always have criminal consequences – a prison term – for the aborting woman and/or the aborting physician, at the national or state level. The Pro-Choice position is indifferent about a) and b) and is only really concerned with c), the question of the criminalization of abortion (should a woman have a legal right to choose, or not, an abortion, free of legal restraint?). For modern Americans, the Supreme Court decision, Roe v Wade, defines the Pro-Choice position, as women are free to have an abortion for the first 90 days after conception (even though any state may criminalize abortion 90 days after conception, and the federal government will criminalize abortion 180 days after conception). Roe v Wade does not “approve” of abortion any more than the repeal of Prohibition approved of the consumption of alcohol; it only made it legal, i.e., an act without legal consequences. Pro-Choice people do not “like” abortion, they just want it to be safe and legal. The key distinction between Pro-Life and Pro-Choice is: do you want to imprison the woman who has an abortion in her first 90 days? If you do not, you agree with Roe v Wade and you are really Pro-Choice, even if you call yourself Pro-Life, even if you vote Pro-Life. I will wager that there are millions, if not tens of millions, of Americans who call themselves Pro-Life but who are really Pro-Choice. But I have no hard evidence to back me up.
