I feel 2014-2015 was their apex. I believe starting in 14 a lot woke up. And a lot more are showing signs of disatusfaction. But because it's a cult and "captive" religion, the tipping could be slow because so many inside that have mind that can wake up, may believe it's only them and fear not being a witnesses.
I agree. Though it might be significant that the two people saying this woke up in 2014.
It seems a lot of the noobs here cite the overlapping generation nonsense as their last straw, and I think putting that out at the beginning of 2014 was a big mistake - I think they wanted to "get in front" of the disappointment of 2014 coming and going uneventfully, but it seems that a lot of people sorta saw it as an acknowledgement that their false prophecies had failed in a significant way and that nothing would happen that year either. Now that everything is settling back into the normal routine after all the hype of 2014 I think a lot of people are going to start looking around and asking questions.
Even without that, the OP seems to do a good job of describing the general state of the congregations around here as well. The "good" elders are getting old. There's a lot of "murmuring" about the new appointees - most are at least 4 out of 5: young and inexperienced, petty, self-righteous, rude, or downright stupid. In my former congregation, they hadn't even lost that many of the older elders yet and they're already getting this desperate. In the next 5-10 years all but maybe 2 elders from that congregation that are worth anything will be either dead or severely limited due to age, and they've already scraping the bottom of the barrel for replacements. This isn't going anywhere good - the intelligent ones from the last generation are dying off and their replacements are idiots that rely only on blind obedience. Anyone in the next generation that has any sense will surely be pushed out.
