This law would change the State's behavior - like no more State sanction for killing innocent unborn children, no more tax money given to Planned Parenthood. Would that mean nobody would ever try to kill an unborn child again? No, but maybe you should think about how more people might be deterred from such behavior if it didn't have legal sanction. It's like laws against any crime. The laws don't wipe out the crime, but they do deter *even more* people from committing them than if there were no legal consequences.
Michael, the Archangel, defend us in battle. Mary, Our Mother, protect us under your mantle.
