Hmm... well, I'll bet you said the same sorts of thing when you were a scientologist. You were probably pretty convinced that anyone who didn't have your understanding was delusional, though you might have said it using different words, then.
Some people leave the Church, but it stays with them.
I'm not sure what comparing someone who only had access to a copy of Dianetics and a list of pipe dreams it claimed to deliver has to do with trying to make sense of the incoherent babbling of an amphetamine addicted con man after you have access to all of his material and know it never even remotely come close to producing the results it promises.
I was never interested in becoming a Scientologist, I was perfectly content with my religion and was only interested in Dianetics, Once I understood that the only goal of Hubbard's material is to make the you Scientologist, I was no longer interested in any of it. Then a few years later when I read the Time Magazine article in 1991, I couldn't believe people continued to waste their time with it and it still baffles me to this day.
