Abortion laws are extremely controversial. Those who describe themselves as “pro-choice” believe that the decision to have an abortion should be left to the mother. In contrast, the “pro-life” faction, arguing that abortion is killing, holds that the state should prohibit abortion in most cases. Feminists (see feminism) (see also feminism) and liberals generally support the pro-choice side; Roman Catholics and Protestant fundamentalists generally back the pro-life side. (See Roe versus Wade.)

The words abort and abortion can also apply to non-pregnancy related topics.
