I think what you are getting at is the question of when "being realized" begins, and while I know that we could be discussing that aspect for days and I would not sway you, what remains either way is the fact that there is no analogy to the topic at hand here.

If you assert that "realization" begins very early, then legislation such as this one applies to the embryo as well. If you do not assert that, then legislation that applies to living humans does not apply here.
