It is just as true as virtually all other religions... Any religion with a dogma is based on fantasy. Really, you have to ask the question? Just because you are rich and/or famous doesn't make you a clear thinker and intelligent person.
It is a cult. The membership depends TOTALLY on giving a HUGE portion of your money to the headquarters. Even wealthy people who have joined (and later gone bankrupt) are forced to stop being members, just because they cannot keep paying for membership. The more money you 'give' the more religious teaching, and indoctrination you receive.
