Comment: Even if we change the law,

Even if we change the law, the state will need to act when the law is broken. We don't need to convince anyone, we need to prosecute. I don't think a prison sentence makes much sense, in fact I disagree with the concept of prison.

I think in this case a fine would be in order. Many abortions are committed for economic reasons, "we just can't afford it", and a fine would take away that disincentive to have the child. Of course, the parents could still give away the child, and be reimbursed the price of the medical bills by the adopting party.

If the mother/father want to avoid having to go through the birth of a baby, then they should keep their genitals separate, or take birth control measures.
