I tend to say pro- and anti-abortion.
Pro-abortion is misleading and inflammatory. It goes again to the idea that the left wants lots and lots of abortions, which is flat out wrong.
Pro-life and pro-abortion are both right-wing distortions.
It could also go to the idea that the left wants abortions for anyone that wants them (apparently regardless of their reasoning). That tends to be the sentiment behind the rabidly pro-choice demonstrators you see at places like the Women’s March, much like the pro-life extreme of being opposed to even the morning after pill. As for pro-life being a rightwing distortion, I don’t necessarily see how. It’s technically accurate.
