In other words, you don't see it as letting her do what she wants with her body. Regardless of whether you want to see it that way, it is telling her what she can and can't do with her own body. My point was a question of why you think it would be deemed acceptable or legal to allow a woman to make that decision on her own in some cases (like rape), but not in others. How is that different from saying that it's never ok to kill someone unless your life is in danger or if you've been raped? Obviously, the first is sort of acceptable. If it can be proven, then you generally won't be convicted, if it's a case of self-defense. However, you might get some sympathy if the person you killed had raped you, but it wouldn't make it legal, and you'd still most likely be convicted of some kind of murder.
So, since, to you, having an abortion is no different than murdering another adult human being, then why would you expect this inconsistency in the law?
