So you're holding the well being of poor children (whom everyone agrees are people with rights) hostage for the sake of not yet viable or autonomous fetuses?
I don't believe non viable or non autonomous fetuses are people. But even if they are, nobody has the right to live if they must be parasitically attached to another person's body, including you or I. Someone can certainly volunteer themselves to save a person in that position, but they can't be legally forced into it.
There's an argument to be made that I can agree with that more developed fetuses that are close to birth and can theoretically survive out of the womb should be extracted alive, but abortions of that kind are an extreme minority of all abortions.
That seems unbelievably evil.
