Hi Sleepy,
I think that my wife & I's response to this is fairly complex.
First lets start simple - we disassociated ourselves just over 1 week ago & had done nothing wrong in the WTBTS eyes so point 1 is out for both of us!
However generally we agree that broadly the 3 points for leaving could well cover most peoples general reasons for leaving however I offer a fourth.
My wife basically left for point 3 [3.We wanted it to be the truth but were overcome by the mountain of evidence against it.]
However I think that I left for the 4th reason I mentioned. I kept trying to keep up with what was expected in the organisation BUT found that I couldn't keep doing it & remain happy. In fact I was getting more & more tired out & was becoming weighed down with guilty feelings.
I also had doubts caused by this since I wanted to do what was "right" & so I hunted around in the literature to see what you ought to do when in this situation. The supposed answer was "more meetings, more personal study & more prayer".
I tried this to the best of my ability (although lets not kid ourselves this was way from perfect!) & what happened? I got more tired, guilty & stressed. For me this is strange since I am very easy going & don't get stressed by much. Hence in the end I found myself asking "can I be an active witness any more? & do I even want to be?"
At that stage I talked to my wife - she had had an issue about "truths" changing but we had not really discussed this before or examined it. So we did & thats when I found lots of evidence AGAINST it being the truth. Everything then seemed to point towards an organisation of MEN changing things/doctrine when it became difficult to maintain anymore & then covering this up as best they could!
Okay so that is my suggestion for a fourth reason for leaving.
Now for the rest of your comments. My wife & I in short think that although there may well be broad headings for why people left the truth, in reality each person is an individual & hence has a entirely unique way of thinking & thus leading their lives.
Therefore it is probably impossible to set general reasons as to why EXACTLY people leave. Yes perhaps older ones feel security in the organisation but there could be a multitude of other reasons why they stay or alternatively leave - there is no easy answer because we are all different...
However we both feel that perhaps the best motivation for people leaving is that they remain TRUE TO THEMSELVES & hence if a person is no longer happy or content that the "truth" is correct for them then obviously they can no longer stay.
My father-in-law might have something to say about this - we get the feeling that he thinks we aren't being honest with ourselves - we don't know his reason for saying this but we can say FOR SURE that he is WRONG... By the way - he isn't even a JW but seems to be more unhappy about us leaving than my mother-in-law who is & is still talking to us!!!!!
Hope this gives you some thoughts to mull over.
Yours S&L
