Hypocrite? No way.
I, for one, wouldn't think that I would be able to continue to serve as an elder after coming to a realization that the WTS is a farce. But I never served as an elder, so what do I know? If it suits you, then proceed at whatever pace bet suits you and take it at your own pace. Let no one judge you. You will know best when the time is right to make a move. Like some others have said, the knot in your stomach and other physical signs will be good indicators of how long you can stand to serve as an elder for the Borg.
I do think that it would be of interest to see how much 'light' you could cast into others minds in such a position while knowing what you do. And possibly being able to subside other wrongful actions at least on a local level would be of interest.
But again, I couldn't even go back in FS once I knew the truth about the Troof. So how one could continue to give talks without blurting out information that would throw up the apostate red light to others in the congregation would be a tough tightrope to walk.
In the meantime, please keep posting and reading here. Some bite here, but for the most part everyone I feel means well and can offer some level of support to you.
Best,
Paul
