So making a point of equating fetuses with human beings is an appeal to emotion, because it is intended to create empathy for the suffering of a creature that as far as we can tell, is incapable of suffering.
I notice you ignored the fact that in my case, abortion was actually a possibility, and (ignoring the impossibility of such an event occuring, once I no longer existed) I would accept the fact of having been aborted, if the choice was my mother's life/health or mine.
I really think you need to show that there is an implicit, but enforcable social contract between the mother and someone, and that the government has the authority to enforce that contract. I think it's obvious that the contract is not between the woman and the man, and that it can't be between the woman and God, because there are people who simply do not believe in God, and yet are quite capable of becoming pregnant. So I guess you can try to show a contract with society, or a contract with the unborn child, but either way I think it will be difficult.
(Note: I don't question, at a basic level, the legitimacy of government, I would be willing to accept proof that the 'contract' is unambiguous as sufficient to allow the government to step in and enforce it, i.e. I'm not trying to make the burden of proof unecessarily heavy.)
