when-life-beginsWhen someone supports abortion on the basis that “nobody knows when life begins,” my immediate reaction is to immediately correct their misinformation with the facts of biology.  Doing so, however, does not always end up with them becoming pro-life.  People will often move the goalpost, offering another justification for abortion.

To prevent this, you could ask: “Does this mean that if we knew when life began – and we found that it began at conception – that you join me in opposing abortions?”  If they say yes, then they commit themselves to becoming pro-life once you have provided them with the biological evidence.  Of course, they could always say no, in which case you might ask them, “If it’s not our ignorance of when life begins that justifies abortion, then what does?”  While this may prevent you from being able to provide them with the biological evidence to demonstrate their error, at least it will refocus the conversation to the reason(s) they think justifies abortion – which allows you to be more pointed in your apologetic, and provides a better chance of them changing their mind.
