For whatever you may view the worth of this, as an until very recent psych researcher in a lab that focused on PTSD and specifically CSA—I finished grad school I wasn’t kicked out for my unorthodox beliefs or anything—I can tell you that is not the commonly held opinion by contemporary researchers and that those cases have not been meaningfully substantiated, despite the huge amount of evidence that would have to exist for the stories to be true, nor have similar events been seen in the following years—despite the Qanon movement’s popularity with local police forces which would seem to indicate willingness to accept these cases as possible and investigate them. My difficulty with accepting the satanic abuse at face value comes down to this, how are archeologists able to investigate and establish ritual sites from the megalithic era but no solid evidence for these major satanic rituals that occurred within the lives of many still living can be located, despite the significant public backing (including in the govt) that existed at the time and again more recently with Qanon to investigate?

Ultimately it’s not my place to say, but in my opinion, this theatrical stuff belies that the vast majority of abuse is committed by an individual known to the victim, not cults the victims and their families weren’t active members of, guys in vans handing out candy snatching kids off the street, or predators in online chat rooms.

None of this speaks to OP’s question about forgetting trauma, but the satanic cult abuse specifically to be clear.
