A key moment in her political evolution, as for many of her generation, was the film series How Should We Then Live by the theologian Francis Schaeffer, who is widely credited for mobilizing evangelicals against abortion, an issue most had previously ignored. A Presbyterian minister, Schaeffer argued that our entire perception of reality depends on our worldview, and that only those with the right one can understand the true nature of things. Christianity, he argued, is “a whole system of truth, and this system is the only system that will stand up to all the questions that are presented to us as we face the reality of existence.” Theories or assertions from outside this system—evolution, for example—can be dismissed as the product of mistaken premises.

That is a very dangerous world view. They can justify and dismiss anything. Sounds very familiar too.
