Welcome to the posting side of this forum. For any readers who didn't get it, PIMOJW means
"Physically-In, Mentally-Out" JW.
I was (extremely shortly) where you are, but couldn't stay there. For my own reasons, I had to get away from it.
I won't lecture you on what you should do, everyone has their own path to follow, but please don't quickly dismiss the idea of stepping away from the elder assignment. It doesn't have to disrupt your JW family if you did it for health, financial, or just personal reasons that cannot be fully shared with family. Okay, done with that non-lecture.
I hear ya about creating a new email and being careful about getting caught involved in anti-JW stuff on the internet. As a faded JW, I still maintain many separate things. I am just less and less worried about it as time goes on.
As for the ideas you suggest here on page 3:
"...another positive of still being in and an elder is that i can hopefully help with the terrible situation surrounding child abuse. many elders HATE the direction they are getting. they either go along with it , or kick up a fuss in a way that gets them removed and dfd. I know the system, i know how to deal with co's, the branch, and even WHQ. at the very least im on hand if anything happens locally.
a number of elders speak openly about their disagreement on issues to do with child abuse, money (being taken from congs, and the begging), treatment of sfts's who were "reassigned to pioneer service" (booted out), khs being sold etc. there is a LOT of dissatisfaction out there, but not a lot of will to deal with it. "
Edited to add: I had comments here and they disappeared.
I wanted to say, you surely could be a big help to an individual in the congregation facing problems about abuse. You could help them to get the proper help.
But I wonder on the rest- did you actually stop WTBTS from getting your congregation funds? Did you prevent the selling off of a KH? I hope I am wrong, but I don't feel that one elder, well-intentioned and knowing their system, can make the tiniest difference to decisions made at a much higher level. I am glad you want to buck the system and stand up for some things. But I will say that you will probably be removed as an elder somehow if you have any success. If they cannot come up with charges, they would simply close and sell your KH and tell every other congregation that you are not recommended to be re-appointed. And I would be proud to be kicked out of the boys' club for such a reason.
