Hi Reservations,
This is just my opinion, but as an elder, you won't be able to help anyone to wake up. In my experience, people wake up when they are ready to, often for personal reasons rather than anything doctrinal or organizational.
I think what is more likely is that, as an elder trying to wake people up, you will be outed in some way and end up out of the organization - the very thing you were wanting to avoid. The WT has built in just too many layers of mind control. Someone will see that your thinking is out of line with the WT and will expose you.
For peace of mind (and again, my opinion) your best bet would be to resign as an elder, get off the school, and stop commenting at the meetings. And give them no reason whatsoever. NONE. This will catch people's attention. Will it wake them up? In my experience, only when they themselves are ready. But you will have the peace of mind knowing that you are no longer supporting something you no longer believe in.
If you give your real reason for stopping everything that I just mentioned above, that in itself may become their reason to put you out. The mind control is just that pervasive. But you may get some satisfaction in withholding your reasons, just like the WT withholds information from the R&F. Give them a taste of their own medicine.
Well, that's my opinion.
