I'm "still in" because I just recently graduated and my current job doesn't pay enogh for me to leave home. And I honestly am so torn, because I love my family and friends, but I hate everything about "God's Chosen, Almighty" Pedophile-protecting Cult. I was a born-in, but I've never truly believed in it. Heck, I was secretly taking part in all of the holiday-related activities at school I could, saluting the flag , etc. from first grade on (as long as there were no other witless kids in the class ).
I still go to the meetings semi-regularly, and will maybe go in the field circus two or three times a month (an hour each time, but I definitely lie on the report...). I don't believe in god. I don't comment, ever. At most I'll read a scripture to appease my mom. I'll subtly bring out huge contradictions in the bible and the society's litter-trash to her, but it doesn't even phase her... she'll maybe just tell me to "do my own research" or "ask the CO next time he visits".
I'm pretty definite that my mom knows I'm mentally out... in addition to everything else, she's read my notes on the conventions before, where I basically satirized everything said from the platform... but she doesn't really bring it up much.
