This thread totally delivers. Best thing I've read on here in days.
Confession:
"Okay, so you don't believe this is the Truth. Well what do YOU say is the Truth??"
Every single JW I've tried to talk to about this, discreetly, has said some variant of that. EVERY SINGLE ONE. And I used to say it, though I approached the concept from a different direction. My take on it was: "Sure, the organization is imperfect and has made mistakes, sure they have some incorrect teachings even now, but is there any other organization or religion that is close to the truth?" That "closest to the truth" argument, though it made some Witnesses uncomfortable (since it's supposed to be THE Truth), is what kept me going as a Witness for many years.
That, right there, is one of the fundamental, most primary, most pernicious of the Society's teachings. Being able to counter that is fundamental. It should be the #1 conversation stopper in the Apostate Reasoning Book.
