Let that night hold no power over you. I've been born-again and God cast those devils out of me. That woman had had an experience and she knew that even something as seemingly harmless as a child's book can desensitize and open people up to evil spirits. They are just as controlled by Satan as people doing Santeria, Voo Doo, and Palo Mayombe. All of the preceding religions mix Roman Catholicism and African shamanism.
Nothing is neutral.
I haven't mentioned music and it's profound impact. It works together with a bunch of other things to control people too. Perhaps that's a story for another day. The bottom line is that the battle is not against the dope dealer or even the Satanist. Viewing death and destruction as a form of entertainment is, in itself, bizarre.
