These things were EVERYWHERE for a time, especially in very Bible-belty parts of the world. Chick’s peculiar and fundamentalist version of Christianity left no room for any other sort, so his tracts denounced the usual ills (alcohol, sex) as well as things like D&D, Freemasonry, versions of the Bible other than the King James, evolution, Harry Potter, etc. He even devoted at least 20 of his tracts to the evils of Roman Catholicism (because, obviously, they’re responsible for communism, Nazism, the aforementioned Freemasonry, and Islam).
Via this thread at MeFi, I found this live-action re-enactment of the Party Girl tract, starring French Stewart and Judy Greer. There’s an issue with the audio sync, but it’s still fanTAStic. Also, in 2014 a group made a short based on the wildly popular anti-D&D Dark Dungeons tract, and I really, really would love to see it, too.
