Some of the research that I have been doing on cults and high control groups, suggests that just about anything can take on those characteristics.
Here is a link to a booklet from Jehovah's Witnesses Recovery. There is an interesting article about High Control Groups in it. It's downloadable. http://members.aol.com/beyondjw/xj.htm
I read Out of the Cults into the Church when I was first leaving. It talked more about mormons, moonies and hare krishnas. Same thought control.
