The fact that the anti-abortion crowd may wrongly bring religion into it would seem to be no reason for you to wrongly bring a different religion into it...especially when Ray and I were seemingly discussing the scientific aspects.
You point about the cost and difficulty in keep said child alive is more valid. However, at this point it is effectively impossible to use medical care to breathe life into the inanimate. Therefore, the fact that a fetus can survive at that point, at a great expense, tends to show existing life.
