I got depressed because of the authoritarianism and legalism. I was constantly in trouble over everything. Going to bed to late, laughing too much while working, listening to the radio whilst cleaning the pool. The Watchtower Society behaves like the Pharisees and nowhere is this more apparent than at Bethel. If you read the book Combatting Cult Mind Control by Steven Hassan it says that to determine if a controversial Christian groups could be a cult a person should observe the way they operate head office. Whilst in Bethel i came to realise Holy Spirit does not direct the organization (elders being promoted whilst committing adultery) and that is what really got me down.
X, Maybe you should read the article about preaching first. In answer to your question, 7 Day Adventist's started at the same time as JWs and have as many followers. That shows their preaching is as organised and effective as JWs. JWs want to believe only they are right, so hang on to whatever they think proves themselves unique. Reality shows that many other Christian religions preach just as effectively. Mormons preach about the Kingdom, just not the JW version of what the kingdom is.
