What gets me here is this particular argument that, and I quote: "the fetus is a clump of cells dependent on the nutrients of mother for survival and is therefore a part of her body."
Gee what about the newborn outside of the womb? You gonna kill them when they're outside her womb and NOT a part of her body too, ya ghoul? If you drop a newborn in a desert and leave it there, they will not go looking for food or water, they will die of starvation and thirst.
Just as dependent outside the womb as they are inside. THIS is where that argument falls completely apart.
I'll be waiting for rebuttals here.
