Its not pointless, its cruel and unusual punishment. Should we be forced to look every animal we eat in the eye before it dies? Should I have to see a bunch of dead babies when I decide that I'm getting a vasectomy? There is absolutely no medical reason to waste ultrasound and doctor resources on this procedure. It is the mother's choice to get in that chair and give the okay, that is all that is necessary.
Anything else is simply attempting to guilt the mother into a different choice. If you want it illegal get it changed, until you do that stop harassing people who are getting a legal private procedure.
