Well, if the female parent decides that the clump of cells is a Blessed Gift from God the male parent is on the hook for about 20 years worth of child support. It's just one of the perks of female privilege. That's how we hold the male parent accountable.You do know how that works, right? It takes two. What do we do with the other participant?
How about, if neither parent wants to raise the baby that they chose to make, they both have to ante up for support. The male parent rather more, since the female parent did gestation duty.
A parent who is not willing or able to provide gets sterilized. I don't expect the Justice system to change the past, but it can change the future.
