Are you Pro-life or Pro-choice?

[Bodhesatva]

This question absolutely comes down to what you define the fetus as.

If we all agreed, right now, that a fertilized, two day "old" embryo was a human -- with all the legal and moral rights that entails -- then I assume we'd all agree that abortions are wrong.

That would be, without any question, murder. It would be no different than waiting 9 months, giving birth, and then dashing the infant against the rocks, because a two day old embryo is as much a human as the baby is. 

But many of us do not believe this, and believe a two day old embryo is not a human, and thus it is not entitled to the rights that a human would be. At some point during development, the "embryo" develops into a "fetus" develops into an "infant." It's difficult to define exactly when those definitions become valid, but I think most would argue that it's when the baby becomes capable of conscious thought, and from what we can tell, that's around the start of the third trimester.

Which is why most people, even pro-choice people such as me, agree that abortions within the last few months aren't just, because that embryo is now a human, and we don't have the choice to take another human's life.
