No one is arguing that fertilized embryos are not life, in the same sense that my cuticle clippings, hair clippings or ejaculate are life. The argument whether they are human _lives_.
Second, even if one was to believe, intellectually, that a fertilized embryo was a human life; I would STILL expect that person to choose to save the actual, breathing, thinking entity. The one that is capable of surviving independently for more that 8 seconds when not biologically linked to another organism. This is something that every human being understands on a deep, instinctual level. The type of person who would make the alternate choice is a sociopath trying to prove a point.
Finally, it would be a mistake presuppose that I fail to understand the opinion of the antiabortionist. I grew up in bible country. I was raised on this shit. I was indoctrinated into these beliefs, and it wasn't until I started examining them under a critical lens that I cast them aside.
