Scientology
(SIYE-in-THAW-luh-gee)
A money cult founded by science fiction writer L. Ron Hubbard. It is centered around the belief that aliens invaded the world and brainwashed us, and that Hubbard is a kind of Messiah whose ideas will lead us to wisdom.

Here's the catch: You have to give lots of money to the Church of Scientology if you want to get in, and they use this money to buy everything from pamphlets to enormous cruise yachts, and because they're considered a religion, they don't have to pay the taxes we do!

Yet for some reason, many people in Hollywood, most notably Tom Cruise, buy into this "religion". And whenever someone tries to reveal the truth about Scientology on a large scale, or accuses the mod larsony, the Scienstapo will harass them by incessant sueing.

So in short, Scientology is just another cult.
Dealing with Scientology:

Scientologist: "What are YOU doing?" <takes out pamphlets>

Random person: "Avoiding a Scientologist."
