I happen to agree that it is worshipping Satan. Perhaps in a different form or manner than the true "Satanism", but worshipping Satan nonetheless. So is Islam and plenty of other religions.
Christianity is an exclusive religion except for the special place it holds the Jewish people. All so-called Unitarian concepts aside, Christianity states you must accept Christ. The opposing forces are of Satan.
Beyond the money making aspect (which I suspect benefits only the upper echelon of Scientology), this is a pop psychology cult. The fact that big name celebrities fall for this given some of the absurdities mentioned in the article and are not ridiculed by the Hollywood set that would quickly denigrate Christians is telling.
Why are they all so afraid of Christianity? Down deep in their hearts they fear the message is TRUE. They don't fear other religions in the same way.
People fear Christianity because it is the dominant religion. I don't think they fear the message. If they did, they would surely convert, wouldn't they? I sure wouldn't want to burn in hell for all eternity for not being a believer. That fear alone should be plenty of incentive to be a Christian.
You're right. The fear of Islam is of a different order entirely.
