The self-given label of the ideological group who believe abortion should be legal and readily available; contrasts with "Pro-Life”.

Until the third trimester, an organism developing in the womb is unable to support life independently, in effect no more alive than a person in a coma with a machine operating his or her lungs. Besides which, Pro-Life supporters—if they really had an ounce of compassion in them—wouldn’t hound women who have made the often difficult and always irreversible decision of having an abortion. Granted, there are Pro-Choicers who don’t seem to think women should grieve or otherwise deal with their emotions after an abortion but I am not one of them: I believe the most important thing for a woman who has had an abortion is to learn how to accept and live with the choice. Emotion is natural to human beings and should be safely expelled rather than corked up. And it doesn’t help to show revolting (and often fake) photographs supposedly showing aborted fetuses, let alone all the other psychotic stunts these people perform (blowing up clinics, anyone? Doesn’t seem very “Pro-Life” to me.)

The act of being for abortion, opposite to the pro-life side, who are against abortion.

A euphemism meaning "woman's right to kill her unborn child."

"Pro-choice" is actually a misnomer, since the issue is not choice, as everyone already has the right to choose, but whether an unborn child has the right to life as enumerated by the Fifth Amendment to the US Constitution.

A group who call themselves this because it sounds better than saying they are "anti-life."

A baby killer
