It really doesn't matter whether life begins at conception or when you take your first breath. It's really a waste of time to even argue about that, because only God actually knows anyway.
Either way, you are not supposed to abort unborn babies, period. Yes you aren't supposed to, but people do it anyway. But if the baby becomes alive with its first breath, that means that if you kill it in the womb, it's probably NOT waiting in heaven to say "It's OK, Mommy, I understand why you did it."
I know people who have abortions sometimes tell themselves that to make them feel better, but I think that if there is no life in the womb, then that fetus - that forming person - is destroyed from existance. Or maybe they are in heaven. But my point is, there's a 50% chance either way, and since we don't know, we shouldn't kill them unless you REALLY want them gone, because that just might be what happens to them.
I know what you're probably gonna say, what about all the "people" lost in the cycle? Well, I know what you mean, but a woman can only have 1 pregnancy every 9 months, that's how we were made. But when we invite a baby to be born inside of us - yes, that's basically what's happening - it becomes our responsibility, and it's not just about the woman anymore.
If you don't want a baby inside you you know how to not have one. Just like if you don't want your lungs filled with smoke you don't smoke. Although, yes you can use birth control if you feel like it, which has it's own serious side effects which make it pretty dumb to take. But if you STILL get pregnant, you have an obligation to give that baby life. Offer to be a surrogate, adopt it out if you must, but don't snuff it out. A baby is the most innocent being (Besides Jesus Christ of course) and you have no idea who it'll grow up to be. Possibly someone great.
Use your brains. Women fought forever to be respected and to NOT be property and to show men we had brains, but now what do we do now that we have all this freedom? Still be with men and then kill babies on top of it? (Not to mention get a bunch of deseases) I'm not saying don't do anything (although I'd like to say that, heh) but if you get pregnant your body ISN'T just yours anymore.
Although if there is something seriously wrong and you're gonna die if you give birth or something, I can understand abortion, but that should always be a last resort, and you should really consider the consequences.
I was speaking kind of generally, I know abortion is a hard thing that's usually not done lightly, but my belief is that it should be avoided at all costs. Those are my thoughts on abortion, I just wanted to share. ^^
