I personally think life begins at the zygote stage, and any other measure is essentially arbitrary. Who cares about if a fetus feels pain or not? You're still killing it-- and the argument of it being a part of a woman's body due to the dependence is also a disingenuous one in my books.
With that said, abortions continue on in every country regardless of legislation, with more complications arising in nations that don't have access to abortion clinics for all citizens.
I've decided that I'm fine with paying tax money letting others abort, but it's something I want never to do myself, nor my next of kin.
I respect your opinion on the subject. I also respect Framers and Howard's opinion on the subject. Believe it or not, to me it's a religious answer. I don't believe in a God that would send the soul back to heaven before they had a chance to breathe their first breath; as such, I could care less if organs are harvested.
