Yes, because I've heard so many disquiting things about Scientology, and I feel that people are getting into it without bothering to take a look at other viewpoints or to really think about it and ask themselves if adopting Scientology is truly a good idea.
I read Dianetics about 10 years ago. It had that "manifesto" feel about it. Like pretzel logic, self-proving argument and explanation. I can understand why celebrities are susceptible to it's allure. They pay so many people to be toadies and syncophants, they need to pay people to say no. It's kind of like the BDSM lifestyle. They want someone to tell them no. And the Scientology temples are more than willing to take the checks.
