You all have good points that I must remember.
I find I can generally focus on the bottom line. Is the fetus a human being or not? They usually come to agreement with that at some point in the argument. Then they change the subject and try to make it about choice again. They always end up talking about the baby being born into a terrible situation. Which to that I ask them if it is okay for a mother to decide to drown her newborn in a tub if she decided not to have an abortion? Why not if it is a matter of choice and we agree that a fetus is a human life?
