"Using certain words in a certain way is something that is done by those on both sides of the abortion issue."
Just making the observation that it's interesting to see how those on both sides of the issue use words. Not just in this post, but over and over again, we read about zygotes, embryos, fetuses, etc.
Dispassionate scientific language is fine, but if those on the pro choice side use only this type of language, IMO it is part of the tactic used to sway public opinion.
Just as pro lifers will say "unborn baby" instead and use pictures of human life in as it appears in the womb, to try to sway public opinion IMO.
