Basically anything you’ve ever heard that involves something “satanic” is bullshit. A psychiatrist and his patient (who then became his wife, in case there was any doubt that the guy was a fraud) published a book in the 80s where they claimed to use “recovered memories” (a thing that is in no way real) to put together a totally fabricated story about her extensive ritual abuse at the hands of satanists. The book was taken seriously, leading to the Satanic Panic, where anyone who wanted attention could claim that satanists were doing something bad and be taken seriously.

By the time everyone figured out that the book was 100% fake (and I do mean 100%) there had been thousands of claims from all parts of the world of satanists doing any number of cartoonishly-awful things. It was so widespread that the rumors persist to this day, despite the fact that none of the claims could be substantiated.

It was basically the precursor to Pizzagate/Qanon. A global cabal of evil (((satanists))) ritually abusing children for a variety of nonsensical reasons, and the Christian right was very happy to indulge in the fantasy because it served their purposes. Wild stuff. Point being, if you hear about “satanic ritual abuse” or anything like it, it is guaranteed to be a holdover from the Satanic Panic and not anything that has ever actually happened.
