I came to the conclusion that it wasnt 100% as much as 10 years before I left. I used to say "It's the closest thing to the truth there is" (cringe) - but that all changed after I discovered the UN letter and read Crises Of Conscience.
But, as we all know, even when we discover it isnt true it's not very easy to leave without your life being turned upside down. I played along for about 6 months trying to fade out until I was reported for "apostate ideas".
