I didn't used to be so pro-choice, but then I moved to Wichita, where they shoot abortion doctors, and launch radio/billboard ad campaigns that lie about the effectiveness of NFP and tell women they're dirty and unpure if they're on birth control pills. I wish I was kidding, but I'm not.
A woman's entire life depends on her choices regarding when she does or does not have children, that's why this is a feminist issue. If you're like me and abortion makes you uncomfortable, you should be fighting to improve sex ed in schools, fighting to improve health care options for women, fighting for employers to make accomodations for mothers and mothers to be. In other words, give women more choices. Because right now a lot of them don't have a choice, that's really how I feel about the situation, and if we make abortion illegal that makes an even more hostile world with a lot less choice. That's not how things get better, it's how people get hurt.
