I am pro-sex education and pro-contraception. Nobody should be pressured into becoming a parent when they don't want to be, but saying you're "pro-abortion" sort of sounds (to me) like abortion is the solution to keep young people from becoming parents before they are ready to be. I think preventing pregnancy all together is a much better alternative than using abortion as birth control. I think abortion should only be a last resort.
I am reluctant to call myself pro-choice or pro-life though, as my feelings lie somewhere in the middle. While I do not think I could feel good about myself having an abortion, I do believe others should have the option to choose, to an extent. It's the late-term abortions that really make me feel nauseous. Why wait until you're five months pregnant to have an abortion? It just seems unnecessarily cruel to wait until the baby is viable.
My sister says she supports abortion at any stage, but doesn't support murdering the baby during a late-term abortion. She thinks a woman shouldn't have to be pregnant if she doesn't want to be, but that any aborted babies who survive should be cared for, since they are most certainly baby human beings, even if their mothers didn't want them. I might be able to get on board with that. But that wouldn't keep me from feeling that a woman who purposefully has her baby three or four months early with no medical reason is kind of selfish. If she's got to give birth to it anyway, why not just stay pregnant a few more months so that the baby won't have so many health problems?
Anyway... I think I kind of get what you are saying - You don't think people should feel bad about having abortions because it causes people who don't really want a baby to keep it... But I'm not sure if I can ever think of the word "abortion" and think, "awesome! Everyone should do it all the time," as I think that could potentially encourage people to be careless and see abortion as a quick fix to their irresponsibility. To anyone who is not a rape victim, abortion should come with the same degree of shame a sexually transmitted disease would. Going in for an abortion probably means you did something stupid. Even getting a tooth cavity filled in is shameful. It shows you were dumb enough to eat a bunch sugar that you knew would rot your teeth. Having to fix a dumb mistake shouldn't ever be something to be proud of.
