TD, what was the name of the French Monsignor? I'd like to read up on him; he may be the founder of all that came after, by the sound of things.
The satanic panic of the 80s grew out of some phenomena that started in the seventies. You had Mike Warnke, who claimed to have been a satanist high priest who converted to Christ.
Then you had that great purveyor of Christian comic tracts, arguably the WT's rival, Jack Chick, and his Chick Publications. He had a series of comics about Satanism informed by supposed Satanist and druid, John Todd.
Later he started publishing stuff by Dr Rebecca Brown, who claimed that churches were being infiltrated and undermined by organised witches. It was a great scapegoat at a time when the popularity and influence of Christianity seemed to be waning. It might have been tempting for the WT to lean into that one, but they already had their JCs and disfellowshipment so, credit where credit is due, they could always claim to be keeping the organisation "clean". The Watchtower was also growing and their finances were fine in the 80s, so they didn't need anything to blame their lack of growth on.
Michelle Remembers came out in the midst of all this. Her story seems to have been popularised alongside that of Laurel Rose Willson, who claimed to be a victim of satanic ritual abuse, to the point where she was supposedly breeding babies to be sacrificed to Satan.
Eventually the whole edificxoe came crashing down when Christian magazine Cornerstone began publishing investigative articles about these people and their claims. Whole "ministries" died overnight when their bogus claims were brought to light.
As for the cartoons and the toy merchandising associated with them, that was definitely being berated in "mainstream" Christianity. There was a book, Turmoil in the Toy Box, about how all that was being used by Satan to usher in the age of the Antichrist. The Smurfs and He-man both got a serve in that one. I'll come back to He-man with the appropriate 80s cartoons topic. 😉
But back to the seventies cartoons and JW kids' relationship to them. What else do you remember?
Speaking of remembering, does anyone remember the British children were tv series, Catweazle? It was about a Saxon wizard transported forward through time, from Norman times to the Twentieth century. It often showcased his occult powers. I can't imagine it would have gone down well in JW households, or mainstream Christian ones, for that matter.
