-_- you do know that abortion rates have drastically decreased in recent years without any changes to the legislation related to abortion, right? Plus, there were a lot of deaths happening due to botched abortions before it was legalized; you aren't saving any lives or souls by making it illegal. Heck, you aren't a catholic, so I don't even understand why you have a problem with it. From your perspective, all those involved in the procedure can still attain salvation, and the souls of the unborn aren't destroyed or sent to hell. That's why I've said before that if I was a believer, I'd want to be an abortion doctor, because I'd save more souls by killing the unborn than I would by preaching. Dark, but true.
Also, the decision to legalize abortion was a political move, not a scientific one. After all, from a scientific prospective, an embryo is definitely alive, albeit not capable of living independently. The legal definition of life is drastically different from the scientific definition. It's no wonder that plenty of atheists are prolife.
