Thanks, all, for the discussion. This is my first nuanced abortion related debate, and I have found the points put forth very interesting. Especially compelling to me were…
This made me think quite a bit. I don’t know if I have the right depth of philosophical background to adequately explain my position, but I’ll try. The distinction that I found most meaningful between the two situations is action vs. inaction. In my ethical view, when looking at a situation of competing rights, positive action which infringes on someones rights should be held to a higher standard. That is, taking action which results in a poor outcome is worse than failing to take action which would have presented a poor outcome.
In the case of the extra-uterine child, nature’s status quo is that the child dies. Positive action (kidney transplant, e.g.) can change that, but compelling it would infringe on the mother’s rights.
In the case of the intra-uterine child, nature’s status quo is that the child continues its free leeching of the mother’s organs. Positive action (abortion) can change that, but would infringe on the child’s rights.
I’m quite open to the idea that my reasoning may be flawed, or my perspective off. Please poke away.

Eh what magical nature is the 3rd trimester for you? Why not divide pregnancy into quarters? The definition I use is not arbitrary at all. Unlike some others, I don’t support the notion of some kind of nebulous sliding scale of personhood. Either you are or you aren’t. And birth and the cutting of the umbilical cord is the instant in which a fetus divides itself from the mother and starts living on his own. Before that, all nourishment comes from the mother’s host body.

I believe that personhood is an emergent quality of the human brain. A group of human cells may be a cancer, blatocyst, or person, depending on the complexity and nature of its brain. I agree that a ‘you are or you aren’t’ line needs to be drawn, but this line should be based on qualities of the brain, not on sources of nutrition or surrounding environment. The magical nature of the 3rd trimester is its alignment with development occurring around week 25 of embryonic age.
