This is more pro-choice double talk.  These people know that we are not trying to stop pregnancy terminations.  All pregnancies terminate!  The only issue is whether they terminate with a live baby or a dead one.  Abortion is not about the termination of pregnancy, but the termination of human life. 

Now, if the question is, what gives us the right to tell a woman she can’t have an abortion, the answer is absolutely nothing.  In a society of laws, no one is allowed to decide what activities others may or may not engage in.  As individuals, we have no more right to tell a woman she can’t hire someone to kill her unborn child than we have to tell her she can’t rob convenience stores.  However, it is right for there to be laws which say she can’t do so.  Just as government has the responsibility and the right to prevent armed robbery, it has the responsibility and the right to prevent the killing of innocent human beings, including those waiting to be born.
