Well, scientology does impose sensorship on it's people. Not to mention that they openly brainwash.
Yeah, that's totally different from other religions.
Most don't /openly/ brainswash. Also, most don't force you to use webfilters that close IRC anytime something sensitive is said, or that close a browser when entering a blacklisted site or when two many sensitive words are displayed on a page.
As a note, these words are not words against Scientologists, but rather actually what they believe. Before hearing the story of Xenu, you must be OT III, which requires many years of service within the church and many dollars given (I see this as allowing them time for brainwashing before giving you some ridiculous, unbelievable at first, core belief.) In addition, blacklisted items also include Scientologist documents (NOTS) which they charge tens of thousands of dollars for, yet are readily available for illegal obtainment on the internet.
I'm not a religious person, and don't see many religions as just, reasonable, or even sometimes valid, but what they do is like a Christian denominations telling you all these stories about Jesus, without revealing his supposed identity until you have listened to them preach about his greatness for 3 years, and have spent $10,000 on your very own Bible (No, you can't get that used, or get the e-book.).
Now that I have said these words (NOTS, OT III, Xenu), I'm pretty sure people using the Scientologist webfilter can't hop on this thread.
