The point is to show that the choice to have an abortion or not is a personal, individual choice
You are 100% correct on this point. I commend you. To sin or not is a personal, individual choice; it is not something foistered upon us.
and that even those who seem to believe with all their hearts that abortion is murder and should be illegal still avail themselves of a safe, legal abortion when they have determined that they really need one.
Those who proclaim abortion to be wrong, yet "avail themselves" abortions are modern-day Pharisees. Their lack of a moral back-bone and insincere proclamations puts them squarely amongst the other murderers.
