How does this show abortion is murder?
Is the state executing a mass murderer wrong?
Was an American soldier killing a Nazi in WWII wrong?
Is a man defending his child from a killer by killing the attacker wrong?
Obviously to you, murder is not always wrong. When is it wrong and when is it not wrong? And if there are times murder is not wrong, what is the objective rule that shows murder wrong for abortion but not wrong for the other clear cases of murder?
If you think murder is sometimes not wrong, then calling abortion murder does not necessarily mean abortion is wrong. Your core point here is to call abortion immoral, not just to call it murder, unless you want to call all heads of states, soldiers, prison officials, and self-defense murderers.
