I honestly have a hard time understanding why anybody would follow Scientology. People have leaked internal documents that make it sound so absurd:
Seriously, just do some basic research on L. Ron Hubbard. Here we have a science fiction writer who "made comments about starting a religion to make money rather than writing fiction." In the leaked documents, we get this story about some extraterrestrial dude named Xenu who dumped a bunch of folks inside volcanoes on earth 75 million years ago or something. That's not even good science fiction. I can see how he came to the conclusion that he should make a religion to make money instead of continuing to write fiction.
