I encountered a little bit of that myself. Certainly not doubts about the organization but more complaints about elders.
I'm pretty sure there are at least one or two other people in my congregation who feel the same way I do but none of us are willing to walk out on that limb.
I've met a few others from this board who are in my part of the country and having an "aposta-fest" at the circuit assembly or regional convention (even hung out with a board member at the international) is such a relief.
The person who actually got me to finally investigate my religion of birth and who is also in the same position as me is a friend. I'm sure he reads this board as well although for the sake of plausible deniability, neither of us have mentioned it.
