Scientology is a spoof religion followed by several high-profile Hollywood stars, every single one of whom is doing it for a bet just to see how long they can fool Tom Cruise.
Advanced followers of Scientology believe an alien ruler called Xenu brought his people to Earth 75m years ago, gathered them round a volcano and obliterated them with a series of nuclear blasts; their displaced souls are responsible for many of mankind’s ills. This is hilariously implausible and richly deserving of open derision, unlike, say, the belief that a man who got nailed to a couple of planks more than 2,000 years ago is your best friend and saviour.
When not being laughed at, Scientology is viewed with suspicion; many members of the public consider it a sinister cult hell-bent on gathering as much money, power, and influence as possible, unlike all other religious movements, every single one of which deserves forelock-tugging respect and unquestioning indulgence of its every crackpot whim.
