Asking questions - It really does depend on the body of elders and your relationship with them to a large degree, unless you go around asking those questions of the publishers and providing them answers the GB would not approve of!
I have asked my body of Elders dozens of questions and I continue to have long discussions with one in particular. I have given them plenty of grounds or excuses to disfellowship me for apostasy if they wanted to. But they don't. They have of course placed a gag order on me and I am only allowed to discuss these questions with them, but as long as I don't go against that they are not disfellowshipping me merely for asking the questions. And they are quite candid in admitting they have no good answers... as you can guess, they always fall back on the good old "waiting on Jehovah."
Shame they can't "wait on Jehovah" to solve the Russian crisis for them - no, in that case they have too write letter and protest!
