Neither 1 nor 2 - hope I can explain this properly
I kind of see it as a switching of mental tracks and it could be ANYTHING that triggers one's mental train (of thought) into moving onto a 'new' mental track that eventually leads OUT OF the WTS.
Just an example: Seeing a new hospital being built in an area where there has been a ton of immigration in the last 30 years and mentally realizing that if everyone thought as the JWs do (that the end is just around the corner and Jehovah will fix everything including sickness and death), there would have been no hospitals built in the last 30 years. Then thinking that THANK GOD there are governments/people who are planning for a FUTURE for all of us IN THIS SYSTEM OF THINGS while the new system keeps DELAYING or we could all be floundering without medical assistance...Hope that makes sense...
Years ago, I heard a brother at an assembly talking about all the 'old worldly people' just literally 'rocking their lives away on the front porch' while 'our elderly ones were BIZZY in Jehovah's service' and my B*lls%&t meter went over the top, knowing this was absolute tripe to be spouting from the platform - it was such a generalized comment that did not fit the REALITY that I knew - that was just one of the things that didn't add up. The total convoluted blood mess didn't help either. So I guess it's just starting to THINK on your own, mentally evaluating what is going on in the organization that I think is starting more and more people on this EXIT. I think we starting to see a veritable flood of newbies because the blinders are starting to come off....
Sorry for how long this is, hope it makes sense...
