Because by agreeing to use the term *something*, the pro-abortion advocates are intentionally devaluing the worth of the unborn baby.
Why should those of us who value the lives of innocent, unborn babies agree to use the terminology of those who value their destruction?
You are absolutely right - that was the point. The language used makes assumptions about the beliefs of the person writing them, especially the rhetorical aims of both sides. That is why agreement on word definition is important, even if it seems pedantic.
I, too, would value the lives of "innocent, unborn babies", put that way. But I don't see them that way for the reasons given before.
WizOz said "Why should
a human, who does not yet possess the above criteria, be unworthy of legal protection?"
I don't believe there exists a human who does not possess the criteria listed, so for me the point is moot. The term 'a human' is loaded with assumptions such that I can't apply it to a zygote. So, the question is not whether I support the 'murder' of 'innocent babies' or 'humans', but whether I consider them worthy of protection in their own rights. Ascribing them to the groups 'humans' or 'innocents' or 'babies' rather begs the question.
We can all agree that the zygote is the object of discussion, so to avoid the loaded terms, the questions should be:
"Does the zygote deserve protection?" given the medical or social issues being discussed.
Zygote has little in the way of emotional effect or implicit assumptions, so is a good word to use. Better than 'something', perhaps, but the effect is to stop the question being loaded so it can be discussed without arguments over the terms.
