I don't sit on the fence at all. I am against abortion except in medical necessity for the health of the mother but I do not presume to make my opinion on the subject legally binding on any other person. Pro-lifers make that presumption and it is morally and ethically wrong and improper.
Thats sitting on the fence. Being a coward. Not having the cajones to stand up.
and what is ethically and morally wrong with objecting to the killing of another human life?
