I'm "Pro-Choice". But I don't have a position on abortion. I'm not female and that decision is a personal one. No one should be able to force someone else to go through with child birth against their will. That is slavery, plain and simple.
Nothing is more important than Life... except Freedom. And the rights of the living far outweigh the rights of people that aren't alive yet or aren't alive anymore.
A mass of cells without consciousness is not a person. We don't know when to draw the line on when to call an unborn child a person, that's a philosophical problem that may never be resolved, but it certainly isn't until quite a ways into the pregnancy and for that reason, we do have protections in place for the child. Six months is plenty of time for a person to make a choice. If you can't decide by then, your judgment probably isn't sound anyway.
I don't think anyone is "Pro-Abortion". It's a difficult choice for anyone to make. Perhaps some people are using it as a form of birth control in areas that provide them for free and that needs to be stopped (if only for economic reasons), but I don't think that's a decision anyone has reached without some degree of emotional anguish. We're wired to be empathetic creatures, after all. "Holy Roller" does have some sort of point there, so long as he/she doesn't try to demonize anyone that has had an abortion, but he/she is putting up a flimsy strawman by attempting to equivocate "Pro-Choice" and "Pro-Abortion".
People have to make tough decisions all the time. Morals are meaningless if your life or freedom are in danger.
EDIT: I mean to say that "Holy Roller" has a point in the sense that someone who actually WANTS an abortion instead of, say, just using a condom in the first place, is probably mentally unstable, "beyond help". Abortions should be a last resort, but are a necessary element for people that need it.
