It has nothing to do with being a minority religion or their doctrine. There are healthy environments and unhealthy environments, both in regard ‘minority’ groups, as well as more popular movements.
It has to do with certain group’s authoritarian structure: the control of behavior, information, thoughts, and emotions.
The pain these authoritarian groups cause is very real. The deaths some of these groups cause is very real. In the case of this forum, the premature deaths, including that of children, exceed any other. Stick around and learn from people who have had life experience in these groups, rather than worrying about whose research is better than whose.
