"And, that product of conception will never "grow into" anything else but another human being. It will never become a carrot, or a puppy, or a pony. "
Karen, you either fail to grasp or choose to ignore the point I was trying to express below. Yes, you are correct, the newly-concieved embryo will never become anythig iother than a Human Being. But, what I wish you would realize and consider, is that in over half the cases it does not even do that. Most commonly it does not implant.
Now, if we really (and I mean *really*) did believe that this newly-concieved embryo was I real, bona-fide, Human Being at the instant of conception, would not that Human Beings own Mother and Father strive mightily to save this Human Being from the grisly fate of being tossed in the garbage or flushed down the toilet as menstrual flow? Might it not be possibel to save and perhaps re-implant tis Human Being, or at least give this Human Being's mortal remains the decent, respectful burial we accord those of any other Human Being?
