There's a reason for that. When JWs lose faith in the Watchtower they do so in thousand different ways. Some accept the Trinity, some don't. Some accept blood, some don't. Some believe in the end times, some don't. Some still believe the Bible, some don't. Some believe in God, some don't. And so on and so on. The idea that hundreds of Witnesses are organizing themselves spontaneously into a community of like-minded doubt is, to me, just not credible.
I agree with you Slim I left at an early age because what they were teaching was not provable reality. I and I suppose a lot on this forum left not out of a conspiratorial overthrow of WBTS but just they couldn't in good conscience preach such bullshit anymore.
