"and the "disposed" embryos/children are armed with what?"
My question exactly. I have had a lot of contact with people who have undergone IVF or who have performed the procedure over the years, and the prevailing philosophy seems to be: life begins at conception, unless you were conceived in a petri dish.
A baby is a baby is a baby. I don't quite understand why the circumstances of one's conception somehow determine one's value, or the degree to which one is considered "alive" at a particular point in his or her development.
I suppose I have a hard time imagining that those petri dishes frozen in time, contain a soul. I could see a soul entering their body if they were growing inside a body...but not in a petri dish, unless we imagine them to be dead.
