“You’re making the assumption that the life of an innocent child is more precious to society than the bodily integrity of an innocent woman.”
No, I am not making that argument or assumption. I make no appeal to the value that society places on someone’s life or bodily integrity. I am making an appeal to the inherent, natural rights that both parties in the dispute have claim to. They don’t derive these from society, so really, society has nothing to say in the matter of any importance. The society could be China, which places less value on the lives of children, or some society that places greater value on them, and the argument would still be exactly the same. Morality and justice don’t change depending on the standards or prevailing attitudes of the populace.
When discussing what American law should be regarding this issue, it's important to consider the broader application of our society's traditional respect for the bodily integrity rights of its citizens. All I'm saying is that, in other areas of American law, the interest of protecting innocent life is routinely subjugated to other important interests, out of respect for personal liberty. A rape exception to an abortion ban is more than justifiable, in my opinion, when you take this into account.
Now, if you wish to make the case that a raped woman has an obligation to save the embryo forcibly implanted in her womb anyway, you have to realize that there will be inevitable consequences to personal liberty generally, when the logic behind that argument is applied to other issues. I would expect that a country with such a law would be very close to mandating blood, marrow, and organ donation. After all, in a society where the protection of innocent life is the preeminent state interest, how could it be any other way?
