There was an elder in my hall as a kid that wanted to make changes from the status quo. He ended up being in various portions of the service committee throughout the years he was elder and took many of the oppressive elders to task for their Pharisaic behavior. In the end of it all he left "the Truth" and is df'd.
That was me, except for the DF part (so far).
As for Metatron's post: It's true you can't just "quit" anymore, but I did and they accepted my decision. There were health issues in my family that appeared quite serious at the time and I exaggerated it even more, so I think they felt sorry for me. But for weeks after that I expected to be told that the body had met and discussed my "request" and decided to "let me" remain an elder without any assignments for a while, "just until you get back on your feet." That's the usual drill these days. But, for whatever reason, they never had that conversation with me. Several months later, after missing a LOT of meetings, I "moved to another congregation." My plan was to go there a few times and then begin the fade. However, we had relatives visit and then we were out of town for several days and the next thing you know it had been a month since we said we were changing congos and, well, it was just easier not to go.
I did get one call from the secretary at the new congo, asking me if there was some mistake because he had received my cards but had never actually seen me at a meeting. I went into great detail about the health issues that were impacting my family and told him to hold onto those cards because, by God, we were determined to get to the meetings at his hall just as soon as Jehovah gave us the strength to do so.
We've been left alone ever since. Looking back, I sometimes think it's because I was a pain in the butt for the Pharisees (see above quote). The guys who would be most likely to hunt me down may feel they are better off without me there, chiding them for their oppressive behavior. But I suspect the truth is that they already know why I left and they don't want to be discouraged by confronting me. I can tell you many stories of elders who just left people drift away because they knew in their hearts what the brother or sister would say if you demanded a reason for their departure, and they just didn't want to have to come up with a good answer for them. It would amaze you how many elders are walking around with heavy hearts, keeping hidden deep inside themselves their own doubts and misgivings.
