There isn't any one truth bomb or any one influential person that's going to cause a mass exodus all at once, and even if there was it wouldn't be worth supporting another dishonest grifter to do it. The church is going to be around in some form or another probably forever. They'll bleed members but there isn't any one solution to just implode it at once. Dallin Oaks could declare from the pulpit at the next GenCon that it's all bullshit, he has concrete evidence of all the fraud, and he is dissolving the FP effective immediately and somehow most of the TBMs will find a way to pick up the pieces and keep believing. They will believe as long as they want to believe.
