In relation to abortion, one who feels that it is wrong to intentionally terminate a pregnancy. Pro-choice individuals tend to call pro-life individuals anti-choice, though this is not necessarily the case. Pro-life individuals generally, but not always, believe that "elective abortions," or abortions for the purpose of birth control (as opposed to abortions in cases of rape, incest, or medical necessity) should be illegal.
While abortion is despicable and should not be considered an option, it is far better to convince one to choose life than to force one to choose life through lack of options. She who chooses life because she cannot obtain an abortion, has not reached the conclusion that abortion is evil; she who has the option of murdering her own child, but chooses life, has made a conscious decision to reject evil.
