Comment by lizmw on The noncentral fallacy - the worst argument in the world? · 2012-09-04T18:29:14.587Z · LW · GW

It seems to me that the left-wing slogan "My body, my choice!" and its variations are a version of the WAitW. Although the slogan itself doesn't follow the "X is a Y" format, its underlying argument does: it asserts something like, "This fetus is a part of my body; I am entitled to do whatever I choose with any part of my body; therefore, I am entitled to do whatever I choose with this fetus."

This version of the WAitW emphasizes the similarity between a fetus and other parts of a woman's body (the part in question is inside her; the part in question is made up of her cells; etc.) while ignoring the relevant differences (most of her body parts, if left to their own devices, will not go on to have their own life outside her body, while the fetus will; most of her body parts have no potential for sentience or moral agency, while the fetus does; etc.) By equating the fetus with her body parts, the argument implies that the fetus is MERELY a part of a woman's body. While most people will agree that a fetus is technically part of its mother's body, I think most people will also agree that a fetus is not morally equivalent to a woman's liver, kidneys, or small intestine. "My body, my choice!" conceals this inequivalence.
