There's so many little vignettes like this in the rise to prominence of the antichoice movement. Schaeffer is one of my favorites, but there's some other really weird little corners.
Another fun one was all these religious/evangelical schools that, in the post-Brown era, were facing down a future where they may have to start paying taxes if they wanted to maintain segregation. These institutions saw that their strictly racist policies were becoming politically unpalatable, so they sought out a way better issue to get that power. Still happening today, by the way, where explicitly religious schools are actively campaigning to get your tax dollars while continuing to teach bigotry and nonsense. Be VERY wary any time you hear a politician mention "school choice".
I also enjoy that Norma McCorvey (AKA Roe) was later turned into and paraded a bout as a pro life campaigner, saying she regretted the abortion and lawsuit and all that. Only to reveal later in her life that they paid her HANDSOMELY to do so and the beliefs and words were totally insincere, she just needed the money. I think that tells you a lot about the underlying moral fiber of these religious whackos.
