Magnumhood, the problem with your position is that there is absolutely no agreement on question of "when does life begin?"
Your position that life begins at conception is a minority position that isn't shared by others, nor has that been the position of society through most of western history. Some say that life begins at birth, most of us believe that it is a process that where life begins at some point between conception and birth. Our ancestors believed that life began at the moment of the "quickening", ensoulment if you will, traditionally was the ability to feel movement within the womb, this is what was written into English common law as to what was defined as murder and, what wasn't.
The authoritarians here believe that this is their business, that they have a legal compelling interest at the moment of conception, but that is a minority position and not supported by current case law.
With that said, abortion is an ugly choice, but a choice none the less. The best we can do to keep women from making that choice is to find better ways at preventing unwanted pregnancies, and to be financially supportive of those who choose to bring life into this world.
