ISLAM DESCRIBED
I came across this description of a cult at GOPVIXEN in her article on the conviction of Warren Jeffs, Church of Jesus Christ of Latter Day Saints. The description was written by former Moonie Steve Hassan. While he was describing CJCLS the description fits Islam to a tee.
"A destructive cult is a pyramid-shaped authoritarian regime with a person or group of people that have dictatorial control. It uses deception in recruiting new members (e.g. people are NOT told up front what the group is, what the group actually believes and what will be expected of them if they become members). It also uses mind control techniques to keep people dependent and obedient. ... Benign cult groups are any group of people who have a set of beliefs and rituals that are non-mainstream. As long as people are freely able to choose to join with full disclosure of the group's doctrine and practices and can choose to disaffiliate without fear or harassment, then it doesn't fall under the behavioral/ psychological destructive cult category."
