Who's arguing? I was just finding out info, you are a curious specimen. It's not common for an atheist to want to overturn roe v wade, not even close to common. Most don't have the chutzpah to want to force their will on all woman.
I'm not even going to try to talk you out of it. You have your own brain and beliefs, and I can't even get pissed at why you hold them like I am at most people around here.
You should read Freakanomics though, aside from being a fun book, there is some interesting analysis of abortion rates correlated to crime rates.
