Sidoh, if you're going to make the, "the baby could be beneficial to society" argument, then we also have to outlaw condoms and force people to have sex as much as possible. Why? Because each baby they don't have may benefit society. So not aboring a baby because it might benefit society is useless to surmise.
Now the problem is, the core argument here is being overlooked as it always is in abortion cases: is an unborn baby alive? People tend to ignore that and preach morality and all that fun stuff, which doesn't further the argument on abortion.
So, the only real problem we have here is AntiVirus's statement, calling abortion "murder". When we kill cows for food, we don't call that murder (unless you're PETA, but that's different), because the animals aren't human. So the question becomes, is the unborn fetus a human?
I don't think anybody can answer that. It depends on your definition of human. Sure it "becomes" human, but so does sperm and we don't outlaw maturbation. So, when does a human, by definition, become human?
Legally, the answer is after the first trimester. Is that the appropriate cut-off point?
