I'm an Australian who has personal experience with a bible based cult and agree with Capt Porridge, cults are an interesting topic for discussion. I hope no one minds that I take this opportunity to point out that Bible based cults can be very dangerous as well the more popular Moonie, JW etc.
To me bible based cults such as the one I've mentioned, is a great example for what happens to fundamental christians when the leaders become more powerful in their own minds than the society around them offers. I get the feeling that leaders of cults have a lot in common with each other rather than the member of their congregations. To me they are a breed apart. Also if you want an example of the 'dangers and absurtities of organised religion' just take a look bible based cults.
As I've stated The Geelong Revival Centre in Australia are a cult, I have a little personal experience with this particular pentecostal type group as well as having four of my family still in membership. I haven't been part of their lives for the last 5 years. Typically I am shunned and doomed to hell for not going along with them. I think the most peculiar beliefs they hold onto is the British-Israel theory Oh and perhaps numerics and pyramidology. Other than that the groups leader is a typical fundamentalist tyrant who owns the entire business and makes up 'rules' as he goes along. This group is also among those mentioned on Steve Hassan's site under the title of Revival Centre International. The 'Bite' model certainly applies.
I've been researching and pondering religion for about a year now. I don't have any formal quallies in religion and find that the most urgent question I have is, how do I live with the fact that my family are living within a cult and that I don't have much power to do anything about it. Its very sad that cults are basically protected by law unless something very drastic happens. I know that in some european countries such as France, cults are monitered but still around the world cults usually fly under the noses of government and society. Its tough when it's not kosha to make comments about someone's religion. That's what I did with my family and look where its got me. If I'd had the social permission to query somone's religion more, I may have questioned it more. I don't know, the Geelong Revival Centre have the appearence of a 'normal' pentecostal religion to outsider's.
