Kewep edumacating them Marvin!
Just an additional though my friend: when someone uses the 'acorns are not oak trees' argument to support killing embryos for their body parts, the answer is "Oh, but acorns ARE already oaks, just not the later form of oak, just as a toddler is not an adult human being'" Being a member of the species does not rest upon some stage or appearance. The life of the individual oak is already alive in the acorn else the acorn could not go through the lifetime stages of the oak. The individual human being is already in the fetal stem cells (and in fact in the placental stem cells and organ) at the first evidence of them, else the human being could not go through all the changes and ages of the HUMAN ORGANISM. The LIFE is in the blood, for humans, because the LIFE is already in the stem cells and continues to be in the stem cells throughout a lifetime.
