IAMA former member of Scientology's 'Sea Org', AMA
edit: Alright, I think I am Scientology'd out for the time being! Thanks for all of the great questions and discussions, it was a good experience. I apologize if I missed any questions and if I let slip some Scientology-speak. Hard habit to break! I added a little bit to my description below to hopefully clarify a few things for anyone who happens upon this as I missed explaining a few things in the original. Sorry about that.
I started working for the the church's 'Sea Org' just before my 16th birthday. In a nutshell, the Sea Org is Scientology's management organization and is staffed by people who dedicate their lives to work beyond full time for the church. I spent 10 years working for the church in the Sea Org. I remained a Scientologist for several years after I stopped working at the church, but began to see rising reports of abuses and also saw an increasing emphasis on money, so I distanced myself from the church and began to take a hard look at the religion from a broader view. I found much of what I'd thought to be true cast into doubt. After well over a year of investigation and self-reflection, I came to the conclusion that Scientology as an organization is very corrupt and that the religious practices do not provide the amazing results that are touted.
Because the church does personally attack people who say negative things publicly about it (I know this from personal observation both from when I was in the church and since I have left), I desire to remain anonymous, so will try to keep personally identifying information out of my answers.
