As an interesting followup to this, a few weeks after I sent the letter, I learned from a very reliable source that the elders in my congregation had a local needs part about my letter. Unfortunately, I heard about it only after the fact, so I was unable to go listen to it for myself. I wrote someone who is still on the inside to ask about the talk, but s/he was unwilling to give any specifics. I imagine that it was the typical song-and-dance about avoiding apostate literature.
The really funny part of this whole thing was that I did not mass-mail the letter. In fact, I sent only four copies to people in my old hall. By having an entire meeting part about it, the elders unwittingly made it a much bigger issue than it was. And if they actually addressed points my letter made - unlikely, I know - then they would have actually
introduced doubts into the minds of the tens of other people who never received a copy of the letter! Those durn apostate elders!
