Oh sweetie, we are discussing innocent humans who are just not wanted. Hardly comparable to some violent thug that breaks into your home attacking you and pistol whipping you.If they won't leave and react in a manner I believe threatens my health or life, I can gut them like a trout if I need to.
Fetuses have no rights; it's not even debatable. Abortion is restricted on the basis of state interest, not fetal rights--and the state doesn't have to interfere at all if it doesn't want to. Fetal homicide laws are based on the WOMAN'S right to carry to term if she so chooses; every FHL contains specific language differentiating it from abortion.
