2: Stepping on an ant is also murder, of an equally intelligent creature unless the fetus was almost complete.
Intelligence seems a faulty definition of life. Are the lives of the intelligent worth more than those of average intelligence, simply because the former are smarter?
4: Unless you're completely deranged, you don't object to an abortion in cases where having the baby will be dangerous to the mother for whatever reason, or if she was raped.
Danger is a slippery concept. Ireland notoriously allows the danger of suicide to justify an abortion. As for rape, how does the morality of killing an unborn child change based on its origin? Abortion will not undo the rape.
