Phizzy: It took a personal crisis to get me to that point, and I think that is what it will take for most people, at least for those who chose as adults to join. It takes a lot to break through the cognitive dissonance, that is why it's so hard to break through to a believing JW.
This is a very important statement.
It was certainly true in my case. When I think about those that have woken up and left the religion, they all had to go through some sort of personal crisis that forced them to confront their beliefs and the unreality and lack of logic or coherence which characterize those beliefs. That often propagates its own personal crisis. It's a process to be sure.
