"The Roe Court supposed that narrow exceptions in state abortion statutes for the life of the mother indicated that prenatal human beings were considered nonpersons. But these exceptions were not based “on a legislative preference for the life of the mother over the life of the child, but on the general defense of ‘legal necessity,’” which is connected to self-defense. Only the impending death of the mother was considered a grave enough reason to consider abortion. The acknowledgement of these rare circumstances “does not demonstrate a lack of legislative recognition of the personhood of the unborn child.” Even if Justice Blackmun were correct that Texas’s exception for the life of the mother violated equal protection guaranteed by the Fourteenth Amendment, it would not indicate that prenatal life is excluded from the Amendment’s protections. It would only show that Texas inconsistently applied the protections of the Amendment."
