I believe your theory it could be correct. I have seen many who were disfellowshiped(immorality, smoking,etc,etc)that they still claim to be JW's.(some they even go back). On the contrary those who leave because they find out that the truth about the "Truth". I believe they are the best ones, since they carry on with their life, erasing their WT past, and leave it all behind for a new life.
But there are also those who were kicked out(like me)who have more anger and they can't go on with their lives. In my case Simon, I was married, having 2 small children to raise, ALL my relatives are JW's, and all of my friends are there, since I was born in the Org. When I realize that for 33 years of my life, I was in a lie and I was really(and still I'm)agry, because of some old fools in Brooklyn, that have stolen my life,and my parents life. I have faced and still facing many problems due to the fact I was a JW. The first issue was the "neutrality" that really cost to many brothers a lot in my country. Going in and out in prison is not a very good for you!!! You can't find a good job if you haven't finish your army, plus there is no way that you will be hired in Goverment jobs, or Banks, or a very serious Organizations if you don't finish your army obligations. The most crazy thing is that the WT had accepted (alternative service)while back in my 20's they strongly reject it. Not to mention that WT was always discouraging education, or even seeking a good job, or jobs like musician in my case that suppose to bring "glory to your self"instead of Jehovah.
I'm 41 years old now and since I left my JW boss, 8 years ago( I worked in 2 JW companies total 20 years. As you guess I was lowly paid) I'm still trying to get a discent job. I do blame the WT for my situation, and I can't find a solution for it,since I don't have time to study, due to the fact I have to work 2 jobs to support my children.
I was innactive for 6 years(since I have chosen not to disassociate from the WT)My "faithfull" ex-wife turned me to the elders for apostasy 2 times. The first was 8 years ago,and the last one before 2 years, when I was disfellowshiped. I'm still agry since this is was not my plan. I would have left but I would have do it with MY WAY. For sure I do not think to go back because I hate that cult with all my existence. I do have 2 small children in there, and I will do my best not to let them brainwashed by the WT.
I do not consider my self JW, and I do not speak regarding my past to anyone.(only in this forum I do that)I'm trying to start a new life, but for sure I'm fighting WT and their evil ways.I do not hate JW's, actually I feel sorry of them because they are misleaded, but I do hate the leadership of this cult.
So Simon I leave on to you to make my pshycological diagnosis!!!
