I know next to nothing about Scientology, but do know it's been around for a very very long time. Although I forgot the title of Ron Hubbard's most famous book (I'm OK You're OK????)I took it more of a self-help type book as opposed to any religion.
Everything I've seen and know thus far, indicates this isn't really a religion as we know it anyway.
That being said, the more I see Tom Cruise speak about it, I must admit he seems a little "out of whack" for lack of a better term.
