They don't consider it a baby or child. Sure the wad of goo is human, but it isn't a person. It has no brain, no feelings, no heart, and according to the bible,(not that I swallow that pile of steaming stuff) it has no soul until it draws first breath.http://www.princeton.edu/~prol ife/articles/wdhbb.html
You want science? I suggest you study embryology. Until then stop with the ignorance.
What you call a "lump of goo" is considered a *human being* by embryologists around the world.
Shove your self righteousness, it is not and never will be your decision.
