It's a dangerous line to walk between criticism and intolerance.
Scientology is one of those things that as a religion is incredibly harmless. It's frivolous at best to mock their beliefs. However, the Church Of Scientology itself is an enterprise not only based on fear, intimidation, profit and power, it's an
extremely corrupt example of it. I don't pretend to defend the organized structure of any religion as immune from error, but in the latter half of the twentieth century the Church Of Scientology has embarked on a campaign of harassment, legal bullying, psychotic behaviour against critics that is endorsed by high-level Church administrators and quite possibly
murder by torture, which may have actually occurred on multiple occasions.
As an additional corollary, there are organizations like
Free Zone who are essentially in the process of a modern schism from the main Church of Scientology. The difference is that where such things were often settled with years of physical conflict and cries of "heresy," it's now being settled with expensive lawyers and cries of "heresy."
And to confound my argument even further, any criticism is good, by the way. Criticism of a religion is no different from criticism of, say, a government. Certainly, there are some people out there who believe in the current American administration, but that doesn't mean that George W. Bush and co. are somehow beyond protest just because some people happen to support them. To suggest that Scientology shouldn't be singled out for protest not only negates previous public protests against the machinations of other religions, but it sets a dangerous precedent. Especially when, although because of their particular self-referential brand of humour the proceedings were a bit bizarre and occasionally cruel, a protest against a religious organization's practices is carried out in as peaceful a manner as this.
I guess what I'm trying to say is this is a complex thing. No point in reducing it to an inaccurate situation of "It's a religion and this is intolerance" vs. "It's a cult and it's dangerous."
