Abortion doesn't go away, it just becomes unsafe....Everyone whose mother and sister took a short unplanned trip alone to Europe in the 50's or 60's probably knows someone who had a legal abortion. Abortion will always be legal for the rich, they just go to Europe.
Sin is a word that to me is a rather pointless when describing something since it's been used to describe anything from murder and theft to things like working on a Sunday, getting a tattoo, wearing two types of fabric at the same time or eating a particular meat on a particular day. And why? For no better reason than the tired old claim "because god said so"
