Cabal Of One
Good points although to be picayune, the church/OSA can even set up a persona with a fake SP Declare. In addition (and I don't know how it happens, really) there are people who have spoken out that they haven't quite gotten around to declaring yet. Anyway, though, your point is well taken.
Leaving has to be a very personal decision. It's nice to have people on the outside, to help when one leaves, but unless people are pretty firm on what they, themselves, have observed regardless of the observations of a Debbie Cook, Marty Rathbun, et al, and have decided no matter what that they will not contribute to that anymore, then they are susceptible to being yanked back in the fold.
In my opinion, one has to be willing to be found out and not care. That's just my opinion. It takes a lot to leave so one better be strong in one's convictions. The very need of a leader is indicative of not having made the transition from cultie to sovereign being.
The secret is, though, that for the vast majority of people, the cult doesn't come after them.
It was a revelation to me to realize, after hearing many people's stories, that Scientology has no come-back if you stand up and resist, ie just start saying "NO" -- even if you're in the RPF. It'll hurt for a while when they try the push-back, but ultimately they can find nothing in their arsenal to counter a straightforward NO.
