Why is the life created by a rape less prescious, less sacred, less human than the life created by consentual sex?
That's what you're saying, here, that life created by rape is disposable if you don't want to accept the responsiblity that was thrust upon you. Is carrying and caring for a child of rape difficult? I presume so, not having experienced it myself. But doing the right thing - the objectively, morally, ethically right thing - is almost never the easier of the two choices.
In saying abortion for rape is OK, but abortion for consentual sex is not, you make a distinction without a difference. Abortion is abortion regardless of why it is done.
