They don't call it pro abortion because many of them aren't actually advocating abortion itself, but rather the freedom of the woman. I'd say that I'm more in the middle on this, although leaning towards the pro choice side. The reason being, is that making abortion illegal would cause far more problems than it would solve. Some people might try to get an abortion in spite of the law, and better they have a qualified doctor perform the operation than some quack in a back alley. It's the sort of thing that is simply going to happen whether we like it or not, and there should be appropriate services in place to handle it. Even back when I was a loyal dub I felt this way.
I do think that killing an unborn child is wrong, especially a fetus far along in the pregnancy. The baby is a life of its own, no matter how you try to deny it, not just a lump of flesh inside the woman's body.
I would prefer that there be very few abortions to no abortions at all, but the world simply isn't ideal. There are instances were aborting the fetus is the better option, such as when the woman has been raped, or if there are serious dangers to the woman's life involved in giving birth. Furthermore, there are cases where having the child would actually be cruel. I hate to say this, but some people simply shouldn't have children. A stupid teenage mother addicted to drugs giving birth will be bringing the child into a world of pain and despair. Or there might be mothers who are in a terrible situation not of their making, who don't want their child to suffer.
It's an very weighty decision, one that should be handled with tearful contemplation before it is made, and one that should be made with a humble understanding of what they're actually doing. I think the reason some people who advocate pro choice anger the other side is because they don't seem to give enough reverance to the life of the child. I.e "It's my body, I can do what I want with it!" Excuse me but its not just your body, its the body of the fetus as well.
However, if the mother has a good reason for getting an abortion, she shouldn't be judged for it.
