I was raised in it, believe in it for years until the hypocrisy of the individuals started to become clearer, dishonest business dealings, cheap cheap cheap brothers who wouldnt pay their JW workers an honest days wage. I remember babysitting after school for 3 children, for 3 hours, and getting paid $5. this was back when getting $5/hr was the going rate for babysitting services of a teenager.
That's just a MINOR example, sorry.
The scandal I saw within my own JW family (about an uncle who married into the family) who had abused 3 daughters (since they were 2 years old!!) and 3 of their cousins, was a former RCMP officer,and was an elder. The other elders did not believe his daughters, He did not get removed until the girls went to court and testified against him. They were disfellowshipped for having a bad attitude towards the elders who did not believe them in the first place.
There are countless reasons why I left, the above posters covered most of the reasons.
I left because I did not want to worship men. They write constantly about how we are supposed to be obedient to the faithful and discreet slave, or the watchtower and bible tract society, yet they will kick you down when you do believe in a prediction, and it doesnt come true and you call them on it. They will blame you for ''running ahead'' of the organization, and not being humble.
You are never ever allowed to question them, ever. That screams of cult.
Do not agree to a study. Do not go to their meetings, this is from a former member who wholeheartedly believed them...
