Roughly 50% of unborn babies are women. I'm quite certain they would not consent to being destroyed if they were given the chance to decide. These unborn women cannot be forced to sacrifice their lives for the convenience of their biological mothers. Using the logic in this statement, these babies shouldn't be able to be aborted even if there is a danger to the life of the mother.

Since we can't violate the rights of any women, it makes sense that we wouldn't be able to violate the rights of any unborn men either. It's only fair.
