Sounds like you've got the whole low down on this crew. Are / were you a member at one point?
I saw what it did to my family. The JW patria potestas concept of 'scriptual headship' and their certainty in the moral superiority of their 'perfect' community from which the sins of 'worldly' people have been excised (which makes them refuse to see evil in their midst) provide fertile breeding grounds for sanctimonious bullies.
There is never any room in the JW world for questioning authority. And for underclass and working poor parents who can barely control their children and keep them away from street culture that order and obedience can seem very attractive. Like a totalitarian state it radiates order and cleanliness and wholesomeness and chastity but at an incalculable psychic price.
This contains a paradox that John Wesley once remarked on. John Wesley noted that when the underclass of his day got religion they cleaned up their act. They worked hard and got off of gin. But this will lead to socioeconomic advancement that will cause them to distance themselves from their earlier faith. JWs who stay in the church remain at the bottom of the socioeconomic ladder. They are utterly without initiative or ambition and the JW religion discourages 'worldly wisdom' (education) and storing up 'worldly riches'. JWs who leave reap the benefits of having kept their nose clean, avoided drugs, crime, and illegitimacy, and retain the fierce work ethic that comes from a 'salvation by works' religion. The Wayans brother, the Williams sisters, etc. Much of the Black middle class came from ex-JWs.
