I honestly believe most JW males stay in the orgnisation because they are given control, i.e. married males have ultimate control over their wives and children. I know a woman who was married to an elder and who said that prior to becoming a JW she would never be submissive to her husband. She said she had to learn to be submissive.
This gives the male power! He knows his wife is less likely to step out of line for fear of being reproved. If she was brought up in the
truth lie she may feel she has nowhere to go if she leaves her husband - so many stay put and tolerate all the abuse that comes their way. I believe many males can see through all the JW nonsense, but to leave would mean reliquishing control of their wives - they'd have to be treated as equals. Oh, yes! They just love having power over their spouses.
