"Pro-lifers" and "Pro-choicers" most disagree over the ruling in D. Roe v. Wade. These two opposing groups of people disagree over the decision to legalize abortion - obviously, pro-choicers believe that women should have a choice as to whether or not they want to give birth or not, whereas pro-lifers are completely against aborting and consider it a murder. In Roe v. Wade, it was decided that women can have a legal abortion, on some conditions.
