But I do want to explain the situation to the elders.
I have a folder full of notes made from my research...
I stopped reading at that point. Nothing you say will matter. No amount of proof or undeniable logic will sway them. They're in a cult. They're still indoctrinated to believe what they're told to believe. They'll follow the rules they're told to follow. And as soon as you start laying out your 'research', they're going to go after you, to have you DFd, then stoned (wait, they can't kill you under current local laws, though if allowed they would).
If you can't afford that, then you have to keep the fade up and use theocratic strategy... lie. Tell em crap. Tell em anything but that you're apostate or you don't believe. This is a war for your sanity and freedom. Do not fraternize with the enemy. These guys aren't your friends. They're loyal to the WTS first.
