My moments were when people rely on the WT for everything that they do, think and believe.
The 2007 KM about study only their materials, then the 4/2010 KM about audio files. It is not about helping people but about dependance on the GB.
Then I put together that they do everything for money - for example the constant deficits for the Circuit assemblies, the guilting of the people and what amounts to francise fees because of the donations of the WWW. Everything is designed to get people to the meetings, to be dependant on the arrangement, and then to donate.
I became inactive when I concluded that field service is a complete waste of time. Do a little door to door, stop at break, then do a few return visits. What a waste of time and resources.
The constant use of Bible characters as illustrations to where I got tired of the Bible.
Then the 5/15/2012 W where it said that if one gets married to an unbeliever that one is disobedient to Jehovah. What does it mean to marry only in the Lord, to them? The person would have to study either the Truth book, or Live Forever, or Knowledge or Bible Teach books. All books written by the Watchtower Society. And then get baptized at Watchtower arranged assemblies, and then go to their meetings. That spells cult.
