I can only hope they lose the end game. I am hoping that one of those "secret" societies that they have bashed (whether the one I joined or a competitor) will expose enough secrets that religion is nothing more than a scam, and all these cults will go down as people refuse to join.
Ultimately, I think they are going to resort to physical force. They are planning a great hounding campaign next year (and I am sure more threads about that will be coming as it gets closer) for those that are inactive. Ultimately, there could be some more serious round-ups of those that are inactive, and it could get messy.
Suicide? Some that leave do commit suicide because they are used to having someone else do all their thinking. They are totally dependent on others to think for them, and cannot make the transition between being active witlesses and going back to the world (the born-ins have it worse in that department). A certain amount of that is expected, and is a fair price to pay to prevent more ruined lives and stagnation of others that would have been suckered in. And those who are able to make the transition to independent thinking will have their lives enriched.
