It's all a matter of punishing women for their own desire to be emancipated, it's a punishment for those women who have sinned by thinking they could act like a man and have sex whenever they wanted. If they truly cared about the unborn, they would
1. care about the already born, first, and 2. push for the widespread availability of contraception.
Given that contraception is bad for them, too, it's clear this is not an ethical question, but a moral one: sex outside of marriage, or for pleasure really, should not be allowed, and it must always carry consequences, no matter if it vastly more impacts women than it does men. You know, a man can always run from their responsibilities, while a woman cannot run away from her womb.
