But making a law like that is just as bad as making abortions illegal. You just wouldn't go to a professional. You'd do it yourself, which is oh so dangerous. Or you'd be like my friend and force a miscarriage. Also not wise, albeit safer than poking yourself with a hanger.
If someone was personally responsible enough, they'd realize that if they're so sexually irresponsible that they have to kill their baby, then they don't deserve to have a baby again and would submit to sterilization.
It's sort of like if someone gives you a VERY nice gift, like a brand new car. If you wrecklessly crash it and destroy it on purpose, do you think you deserve another brand new car ?
I don't think so.
