My resident troll asserts that the woman has an absolute right to kill her fetus because it has committed the unforgivable crime of being inside her body.
Important point: SHE is the one who put the baby there in the first place.
Arguing that the mother has a right to kill the baby because it's trespassing in her body holds as much water as trying to argue that a kidnapper has a right to kill his hostage because she's in the trunk of his car.
Sorry, Mr. Troll, but that doesn't cut it. Try coming up with a valid argument. You can't have a right to kill somebody for being where you put them in the first place. If you don't want them there, don't put them there.
