The time period in the article is too short. However, when I grew up, abortion wasn't an issue for Protestants, which was the dominant religion where I lived. They considered it a Catholic issue. Abortion became an issue after Republicans began to implement their southern strategy, raising it as an issue to bring evangelists and fundamentalists into their religious right coalition. They created pamphlets, movies, meetings, etc. to make abortion a religious issue. As their propaganda campaign developed, you could watch abortion spread as an issue in Protestant churches through the 1980s and finally become an issue for the majority of white evangelical and fundamentalist Protestant by the early 1990s.
