Alive technically, but it doesn't feel pleasure or pain, think, learn, or have even a rudimentary self awareness the way humans do. Is it not yet apparent to you and anyone reading these comments that what you are defending is the termination of the human lifetime begun at conception? You defend the arbitrary assignment of less worthy because of the age attained along a continuum hallmarked by form and function of the human organism, I suppose, simply because you want these individual humans cannibalized prior to their reaching the arbitrary point that you would stamp them worthy of reaching other ages along the continuum.
It's merely undiferentiated tissue in the process of running some genetic and chemical instructions which will eventually turn it into a human being, if all goes well. That is surely one of the most obtuse defenses of cannibalism I've ever read! "... if all goes well" is to be raised in defense of making certain all does not go well for the individual conceived life, so that that individual may be exploited for its body parts. An interesting turn in defense of modern cannibalism, I grant you that.
