Sounds like you would beat her on the stomach til the grandkid was as dead as Terri Schiavo. You and "mercy" make a great team.
You have a wild imagination. She'd have a medical abortion at the best clinic I could find, within 24 hours of my discovering she was pregnant.
But you would usurp gov's parental rights? Agree with him or not, it is his legal right as long as abortion is legal.
