The termination of a pregnancy
. Abortion, at the very least, needs to be left open as an option in cases of rape (so as not to further victimize the woman by forcing her to carry the child of her assailant), incest, and when the mother's life is in danger (as in an ectopic or tubal pregnancy, which will kill the mother if carried to term). Dangerous "back alley" abortions would also result if abortion were banned completely. An interesting contradiction in terms is that supposed "pro-lifers" also tend to be in favor of the death penalty, and have a real bad habit of shooting doctors and blowing up abortion clinics. It's also very difficult to decide exactly when life begins. By Pro-lifer logic, masturbation would probably also be considered murder, as sperm are technically alive and somewhat human (haploid). What they don't seem to understand is that there's a difference between something that is merely "human" and a full-blown, sentient "person." Admittedly, abortion is despicable when used merely as an alternative form of birth control (instead of the pill or a condom), but it's a woman's right protected under the law.
