Some classic tomfoolery from evangelists of the 70s, via io9 (of all places!). Apparently just because people believe in pyramid power and demonic influence, they’re de facto evil and worth preaching against — thus increasing their viewership when the evangelical preachers advertise them to the impressionable youth of their flock.
I suppose I can’t blame them — they hadn’t heard of the Streisand effect at that point. Finally, though, thanks to this video, we have definitive proof that disco is evil!!!1
(Ignore the fact that I’m totally grooving to that song right now.)
