I don't know about scientology being dangerous or not. It does appear that public criticism of scientology can be dangerous. Check out "operation freakout" on google or wikipedia sometime. It's actually very entertaining. These people must register a 10 in the old crazy meter. Check out their beliefs and practices too. No wonder they try to keep it all secret. Anyone who buys in to it has to search desperately for something and easily duped. I did read that hypnosis is a part of the process too. The thing most in danger appears to be one's bank account as it is very expensive to get to the higher levels in the process.
