Pro-abortion? This means that women WANT to have abortions.   I think you mean pro-choice, whereby women have the right to either have an abortion or a full-time pregnancy.   The freedom of speech, to own a gun, to vote, get a tattoo I will regret in 20 years and if I'm a woman the choice to have an abortion.
