That said, the eschatological worldview of Family Radio is not substantially wackier than evangelical Christians (40% of Americans!) who believe that Armageddon will occur during their lifetimes. However much of a scam Family Radio’s end times prediction was, it probably won’t have the kind of long-term effect that far-right evangelicals, dreaming of the Second Coming of Christ, have on American foreign policy with Israel.
Yes, Harold Camping’s prediction of the end of the world was irrational and probably dangerous for his followers. But it’s no more irrational or dangerous than views that are entirely mainstream in American religion.
