Fair point. Let me elaborate. To be more general, the person is inalienable, as an extension of the will. So, for example, if I signed a contract that said you could legally chop my arm off 3 months from now, that contract could not be enforced; for to do so, in violating my physical body, you have violated the objection of my (current) will. The will is mutable and ever changing. That is why the individual as a whole, in addition to the individual’s will, is inalienable. Now let me add that this is presuming your body is attached to you, and you have not legally sold a part of your body to someone else as property. Once a body part is no longer attached to you the individual, it is no longer ipso facto attached to your will.
Good question. This once again relates to the matter of the inalienable will and person. If the mother’s will is not to have the fetus in her womb - that the fetus is a parasitic invader of her person - the fetus can be evicted. So it’s merely a matter of if a woman wants an abortion. Now, if the woman wants the child in her own womb (inside her body according to her will), it would be a violation of the rights of the fetus and the rights of the mother for a man to shoot the fetus in the womb. I see the mother as having some property right in the fetus, as well as the self-ownership of her womb. The fetus is not a parasitic invader if the mother does not want to evict it from her own person, and hence is entitled to the full negative obligations of any other individual. The moment the mother does not want it, however, it becomes a parasitic invader, as it violates her right in her person.
EDIT- You ask about my proportionate punishment stance with relation to this. Well, you see, the fact that the fetus violates the mother’s very will and body makes this different than any other scenario. If a man climbed into your stomach and decided to live there, I would say you could evict him, even if this killed him. Why? Simple. He’s violating your inalienable traits, which is a far greater offence than violating that which is alienable. Consider the difference of degree between theft and murder. One of the chief differences between the two is that the latter violates entirely the individual’s body and will. The same could be said of why slavery is so great a crime. Now, how great a crime is the fetus’? Well, we know one thing. What the fetus did, the mother can do in proportion. The fetus appeared in the womb, due to intercourse, so the mother can do the opposite and proportionate act: evict it from the womb. This is regardless of whether it dies or not. Now, you may apply this to property owners’, and ask me such questions. Well, the thing is that property, contrary to the person, is alienable.
You ask about partial-birth abortions. My stance is if the mother consents or not. If the mother consents, it is legal to evict the parasitic invader however she pleases.
