I really feel for you guys. I did it for almost 2 years before I finally stepped "aside". You can be a little bit of protection from some of the overbearing elders but likely you were like that before you woke up. You can try to plant doubts but if other elders are paying attention, that could arose suspicion. It's a crap shoot. Plus, you have the fact that many aren't really paying attention at the meetings anyway. Ever try having a serious doctrinal discussion with an average JW? They don't really know their own theology very well. It used to frustrate me when I was "all in" because I felt like many would make fun of people of other religions not understading their own theology while not being able to explain the "deep things" of JWism.
I agree with MLE in that most of the issues elders deal with are not of a doctrinal nature. I honestly can only remember one time in 10 years that I dealt with a doctrinal question and it was having to do with taking blood fractions (I just gave them the list of things that would get you DAed and things that would not). The majority of things brought up to individual elders are personal problems and the rank & file feel like they can look to that person for guidance. Once you're not an elder, most folks won't ask for that type of help any longer from you even if you were an "approachable" elder.
I think hardest part is having to give parts. Even question and answer parts are frought with pressure because you have to present the company line yet there were times that I wanted to say what I really thought. Especially when it comes to all the parts giving glory to the GB. Elderelite - wow, WTC?? I have a hard enough time not rolling my eyes just sitting in the audience or reading from the platform!! I do understand though that with a small BOE, it's hard to just drop that task without major headaches (unless you just wanted to DA which doesn't sound like a viable option).
I tried to tell myself that I could act as a spy and at least leak things the WTS wanted to keep private. I did some of that and certainly appreciate the contributions made by those who still have access to that information. But, the stress ended up taking its toll and I finally pulled the trigger.
In some ways, it's like being in the mob. When I resigned, the PO (now COBOE) told me "you can't just quit, this isn't like a secular job". In some respects, that's the way it is. They can whack you in a heartbeat but if you try to walk away, they get very upset.
If/when you guys get to the point you resign and you want to fade or at least become a non-entity in the congregation staying around for family, you will need to lay the ground work. It took me several months of planning and making subtle and not so subtle comments that my family committments were getting too heavy for me to continue. Basically, the rumor mill will go into high gear when they announce that you're no longer serving or have been deleted (can't remember the verbige now). I got in front of it by making comments to those I knew loved to gossip that I didn't know how much longer I could serve due to the pressure of taking care of my family. Plus, some of the elders that liked me also told a few others that I wasn't "deleted" and didn't do anything wrong.
So, while there were a few gasps, there were enough people that knew it was coming to head off the really nasty rumors that sometimes happen.
It's crazy that you have to plot and plan about quiting a volunteer job, but such is life as a JW!
