I've heard those arguments right on this site.
Couched in slightly different terms. People start to froth at the mouth when they talk about the horror of bearing a child that "might" have a birth defect or "might" die, or "might" have other issues.
And today they talk about protecting the earth from overpopulation, as well as protecting the quality of our "breeders"...nobody steps up to remove themselves, but they're all about removing the dead weight of the elderly, the babies of the poor and drug addicted, coma victims, etc.

Didn't think so.
You are all for saving fetuses, until they turn into actual people. Then you don't give a crap.
