This is a silly argument that I've only seen made recently. If I invite someone onto my airplane, am I justified in rescinding consent to them being on the plane, and chucking them out at 15000 feet? Of course not. Even in the case of never having given consent in the first place (e.g. stowaway) that would still be considered murder. To me, it all boils down to when a fetus has rights as a human, and this so called "forced" use of someone's body is a red herring.
