I’m very glad you escaped it.
Seeing those 1980s VHS instruction tapes really brought me back; I remember hearing a little bit about these kinds of things back then; the 1980s was an era of “deprogramming” young people from various cults.
But then the “deprogramming” in many cases amounted to kidnapping and abuse.
I’d see the various 60 minutes shows and 20/20, never quite sure who the good guys and bad guys were in all of that stuff.
My lesson learned was stay away from anything too intense either way
