It's much, much funnier, though.

Scientology was created by a science-fiction hack who was extremely prolific but still wasn't satisfied financially - until it was half-jokingly suggested that he start his own religion. Seeing that such a thing seemed to working out well for that other great huckster of the 20th century, Ayn Rand, the writer thought "why not?" - and thus, another crazy cult was born.

How about, "I doubt that Scientology is any more harmful than Christianity."? Given the relative youth and low numbers of Scientology, you'd be right. But if you were to get out a slide rule and compare how much each has actually harmed people (through direct actions of the church) since the inception of Scientology, you'd be wrong.

percentage-like at any rate.

What MissN and Wes said.

*time travels to a thousand years in the future to discover that scientology is now the dominant world religion and countless wars have been fought involving it.* Don't laugh... you'll see. ;)
