This is probably the best answer based on the stuff that I've heard.
During the first term, a local talk radio show had a woman on who grew up in a cult. She was born into it. She described her own story about how she learned what was happening and eventually got out. IIRC, her parents cut all ties with her, as that was the way of the cult. Anyhow, she described the process of "deprogramming" someone and it is basically along the same lines of what you describe.
Sadly, it's easy to "mass convert" people to cults, but deprogramming is a one on one conversation over a long period of time.
Electric heaters are wasteful. How about spending that energy wisely while also generating heat?
