Got Humanity?

People seem to be deciding first what they want (ESCR, fetal tissue harvesting, abortion), then choosing a definition of "human" that puts the embryos/fetuses/babies they don't want on the wrong side of it, then coming up with some sort of argument as to why their definition of human is sensible and not self-serving.

In my time reading this site, I've seen pseudo-religious arguments for formation of a circulatory system being the dividing line, the formation of a nervous system, the development of rational thought that takes place after birth, and now implantation. I even got exposed to Nancy Pelosi bringing up the cutting edge of Thomas Aquinas' thirteenth century biology to make a point. Half of these arguments make medieval Scholasticism look downright sensible.

I've seen "embryo" swapped out for "pre-embryo" and "blastocyst", and "personhood theory" treating humanity like some kind of prize awarded by a panel of judges at a quiz show. It's starting to become genuinely disorienting.
