I got my wife out and I directly helped a friend leave. I also indirectly helped 2 others, one of whom also helped me. I think I've also convinced my dis-fellowshipped sister in law never to go back, although the local congregation has already done a really good job of alienating her. I just delivered the coup de grace. I know one I have helped has also helped others out and so on.
The problem the organisation has is their own idiotic policies. They have a large number of resentful people trapped in congregations who are unable to leave. Like a cancer they eat away at the other members. Lets just hope it's terminal.
