and believes a human comes into being at the moment of conception then the only reasonable circumstance for an abortion would be to save the mother's life.
To say that there are other extenuating circumstances is bunkum.
Rape? So you, Joe Pro-Lifer, condone the killing of a child due to an unwanted participant of the mother?
Incest? So kill the child because of possible birth defects or embarrassment?
Birth defects? See above. So kill the child because it will be inconvenient to manage?
If you have "extenuating" circumstances to your pro-life beliefs besides saving the mother, you are full of shit.
