This site could help you, save you wasting a lot of time in a benign or destructive High Intensity-High Demand group; it has a fresh take on cults and isms and provides a questionnaire on its home page for those who think they could never get involved in a cult. Please think and reflect before making that assumption; such an assumption lessens your empathy for those of us who were in a cult. We did not think or know we were in one at the time; maybe it dawned on us slowly; maybe we only realized it after we left!
The image is Livia Bardin's book available at International Cultic Studies Association; it is a how to book for parents and friends of those involved.
