No, it's not OK to "kill" a baby if conceived by rape, incest or medical necessity. But it is far more palatable than killing babies because a woman (and presumably her mate) could not take enough care not to conceive as a result of their actions. Are these people telling us that they fought for safe, legal abortion, so they could engage in unprotected promiscuity with no regards for the lives that they might beget? I get it, they want a woman to have control of her body, but not control what consequences her encounter might have. You just can't justify killing as a convenience.
