The word “conversion” fits the abortion-rights cause awkwardly. There is no progressive equivalent to Priests for Life, a website cataloging the stories of sidewalk protesters-turned-Planned Parenthood donors. Abortion rights were, in the beginning, a public health issue. Opponents started framing the cause in moral terms—something that defenders were at pains to avoid. The president of the Association for the Study of Abortion, Jimmye Kimmey, is credited for coming up with the phrase “pro-choice” in 1972. She preferred, she wrote in a memo, because “what we are concerned with is, to repeat, the woman’s right to choose—not with her right (or anyone else’s right) to make a judgment about whether that choice is morally licit.”
