No, its true. Evangelicals have been massively radicalized by the right ever since the 80s. This Politico article goes over the history of the rise of the radical right, and they discuss how abortion was only used because it was more convenient than their actual goal. Some choice quotes (emphasis mine):

The history of that movement, however, is more complicated. White evangelicals in the 1970s did not mobilize against Roe v. Wade, which they considered a Catholic issue. They organized instead to defend racial segregation in evangelical institutions, including Bob Jones University.

The historical record is clear. In 1968, Christianity Today, the flagship magazine of evangelicalism, organized a conference with the Christian Medical Society to discuss the morality of abortion. The gathering attracted 26 heavyweight theologians from throughout the evangelical world, who debated the matter over several days and then issued a statement acknowledging the ambiguities surrounding the issue, which, they said, allowed for many different approaches.

“Whether the performance of an induced abortion is sinful we are not agreed,” the statement read, “but about the necessity of it and permissibility for it under certain circumstances we are in accord.”

Two successive editors of Christianity Today took equivocal stands on abortion. Carl F. H. Henry, the magazine’s founder, affirmed that “a woman’s body is not the domain and property of others,” and his successor, Harold Lindsell, allowed that, “if there are compelling psychiatric reasons from a Christian point of view, mercy and prudence may favor a therapeutic abortion.”

Meeting in St. Louis in 1971, the messengers (delegates) to the Southern Baptist Convention, hardly a redoubt of liberalism, passed a resolution calling for the legalization of abortion, a position they reaffirmed in 1974 — a year after Roe — and again in 1976.

When the Roe decision was handed down, W. A. Criswell, pastor of First Baptist Church in Dallas and sometime president of the Southern Baptist Convention, issued a statement praising the ruling. “I have always felt that it was only after a child was born and had a life separate from its mother that it became an individual person,” Criswell declared, “and it has always, therefore, seemed to me that what is best for the mother and for the future should be allowed.”

Hell, as noted later in the article, Falwell didn’t even start bitching about abortion until like 5 years after Roe.
