I'm a pro-lifer. But most of my reasons (REASONS, not arguments for, which is different) are based on personal beliefs, and things that cannot yet be proven one way or another.
So until I can find arguments that are worth putting in, I think I'll stay out of this. I just wanted to address some side-issues that came up here...
What interests me is that the majority of people against abortion are Christians, and they play the "soul card" fast and heavy... Saying that you're endangering the child's immortal soul, that you're preventing the child from having a chance in this world, etc etc etc...
And yet, by their VERY BELIEFS, all babies that die are AUTOMATICALLY sent to Heaven to sit by God's side and yak it up with Jesus the Christ himself.
I can't speak for the others, but as Catholics are among the most vocally anti-abortion, I hafta say this one argument, when used against them, doesn't fly. We don't believe babies that die go to heaven. We believe they get sent to Limbo, which is not the same.
Note that I'm NOT saying the "soul card" is a valid argument in a proper debate about abortion. The existence of a soul has yet to be conclusively proven. I believe in it, but I recognize that people who DON'T aren't being irrational.
I also want to note that the argument "They can't be against abortion, when in-vitro is okay!" is similarly invalid, at least it SHOULD be, because IV is in fact against the teachings of the Catholic Church.
But if you were speaking of another faith, then all I've said may not apply.
