From the Daily Kos:
No one, neither the patient receiving an abortion, nor the person doing the abortion, is ever, at anytime, unaware that they are ending a life. We just don’t believe that a developing embryo or fetus, whose mother cannot or will not accept it, has the same moral claims on us, claims to autonomy and justice, that an adolescent or adult woman has. I have never seen an abortion decision entered into lightly by anyone involved. The decision to have an abortion is most often made in the time of the first great personal moral crisis that ever faces a girl, a woman, her family and the people who love them. It is only those who stand outside and condemn the women and families who are faced with these dilemmas who take lightly the decisions made in these straits and trivialize the circumstances in which they are made.
Moral dilemmas are always about difficult problems. Decisions between right and wrong are not moral dilemmas; decisions between right and wrong should be no-brainers and should never be difficult.
