and the link for your “history” is?
You see a building on fire and hear a child screaming for help. When you enter the burning building, you see that it is an in-vitro fertilization lab. To your left is a 3-year-old girl cowering fearfully in the corner, screaming in terror. To your right, on a table, is a tray of a dozen fertilized ova waiting to be implanted in womens' wombs. The ova had been extracted from the womens' ovaries and fertilized just hours before with their husbands' sperm.
The fire is spreading and you only have time to rescue one or the other. Do you rescue the one human being in the corner, or the twelve human beings in the tray?
Once you have come up with an answer to that, let's make it even more difficult - the child is your daughter and two of the fertilized ova are from you and your spouse.
I'm not trying to be a wiseguy here, just to add some depth to an issue that is usually rendered by both sides into simplistic excluded-middle (black-or-white) positions.
