Anti-abortion-rights lobbyists talk about how a fetus reacts to pain.

So what? An earthworm reacts to pain. Do they plan to make fishing with live bait illegal?

A reflexive response by the nervous system proves nothing about the humanity or development of the fetus. People in persistent vegetative states can also show a pain response. A cow responds to pain; how many of those activists (I'm guessing precious few) are vegetarians?

Their ideas have nothing to do with science, and nothing to do with the sanctity of life. They're simply grasping every straw they can reach to try and "prove" that a human fetus is "a person from conception", which is a meaningless concept. Do they mean that from the moment of conception, that zygote can compose a symphony, do math, play tic tac toe? Or do they mean that it has the potential to do these things? In that case, every sperm and every egg has the potential, and the next step is banning birth control.

But then again, that's where some want to go anyway, I'm sure.
