From another thread, more appropriate here.
NaturalWay: First, I've already tried to establish that it is a demonstrably separate body-- not her body.
To say it is not her body is not the same as saying it has personhood. If it has no personhood, it has no rights which trump hers.
Now, don't go down the road I predict you might, that it is entirely dependant on her for everything. Not only would it be irrelevant, but opens up the ethical possibility of infanticide, which would be a completely new topic.
No need to get into those issues. Whether it is dependent on her or not has no bearing on personhood.
Second, it is not force. For example, I almost always drive without a seatbelt. I do this even though it is illegal. (Sometimes I even drive above the posted speed limit Isn't the seat belt law an attempt to control my body? It fails to do so.
Not force? You haven’t told us what the penality will be for breaking this proposed law of yours, but I wager it will be grater than that $130 traffic ticket of yours. If you elevate a zygote to personhood, surely abortion will be murder, and we know what penality Christians want for murder. If penality of imprisonment and possibily death isn’t force, I’d like to know what is.
Let's not lose sight of the putative "goal" here-- reducing the number. There is precedent in civilised countries for such laws. Forced sterilazation is a barbaric, monstrous suggestion because it preempts the event of the pregnancy.
Surely not an ends justifies the means argument?
There is precedent in civilized countries for many barbaric things. Which others would you have us adopt besides executing (or imprisoning) a woman for terminating a pregnancy?
