I read Dianetics when it first came out. It didn't do much for me.
Based only on the little I know about Scientology, I suppose just about anything could be a religion or a faith of some sort. You know, like "The Church of the Wooden Spoon" or something. But why not call it a lifestyle instead of a faith or religion? It's just too weird and sci-fi for me to consider it seriously. :-3
