Anyone with half a brain (who isn't trying to kid himself with illogical excuses) is pro-life, because of course unborn babies are people too, what else could they be? Noone deserves to die because YOU made a mistake. It not about freedom of choice, because what about the baby's right to choose to live? Does he not have a choice too? It's not the woman's body either, because while that baby might be inside the woman, he's got his own body that isn't hers.
What is it all about? It's about not taking responsibility for your actions. It's about sterilizing sex and making it all about what I can get out of it and nothing about what I can give in it. It's about taking the easy way out.
What hero takes the easy way out? What an inspiring movie that would make, a hero who didn't do what was right no matter how hard it was. A hero who never sacrificed anything for a greater good. Abortion assumes that we are not capable of being heros, that we are not able to take responsibility for our actions, that we are not able to do what is right no matter how hard it might be. It makes us out to be really incapable people. That is a lie.
Just to prove that you don't need to be religious to be pro-life, here is a pro-life atheist site. These people, not believing in eternal life of course, are horrified at the thought that these babies are being robbed of their only chance to BE.
And just so you know, you can be feminist and pro-life too, like this site proves, who are basically of the opinion that if a woman feels that she has no choice but to abort, it is because we, as a society have not yet done enough for women and their children.
