No argument. Well, rather, let me put it this way; I'm not claiming that scientology is anything other than a peculiar brand of sophistry / mind control, money and power extortion scheme wrapped in the cloth of metaphysical and spiritual philosophy, which was stolen from various and more insightful source material, with a side of campy 40's and 50's science pulp-fiction.
Excuse me while I go philosophic for a moment...Scientology, like academia, religious teachings, and indeed, many political philosophies, condition the mind with various filters which operate on a conscious and subconscious level, where the mind is altered in its perception of the universe. First, these filters start out small and relatively harmless. So, we have "Why don't you take a free stress test", they use that as an opportunity to inject some memes into the brain, and even a relatively care free person now has a huge set of problems, and only they have the solution. Ten to fifty thousand dollars later (however deep their pockets are), this person understands, in his heart of hearts this system is out to save humanity. Deeper in, that individual is gaining the powers of a god, through which only he can save the souls of billions of people.
Little different than the US communist party's strategy through the late 40's to 70's. They get their claws into some naive and impressionable cute thing, who then becomes a recruiter (even if she isn't conscious of her role), to any number of horny young men who will gladly go to a meeting, write their name down and receive a free copy of the communist manifesto or whatever--if there's even the slightest possibility they'll get to fuck. And you know, the ideas on their basic level seem innocent and even positive enough.
I've noticed a big change of political tactics, especially regarding gun control in the wake of our recent mass killings. There are a few new memes being bantered about in the media. "Weapons of war" is my new favorite. They used to call them 'assault weapons', but I can only guess the idea that any weapon is an assault weapon if it's used in an assault confounded some people. It ignores that any number of useful and common implements in this society have existed as weapons of war at one time or another.
After all, once upon a time, a lowly musket ignited by flint on steel was at the cutting edge of infantry warfare technology. Secondly, it construes a mental image, especially to the uninitiated, that differentiates a scary looking rifle from a less scary looking hunting rifle, even if the hunting rifle is arguably more lethal in many ways. "Even if we can only save one life, we have to take action" That's the icing on the cake.
The real question to ask is this: is scientology any more or less dangerous than other belief systems in the wild? Up until now they've been more of a predator on the individual and familial level. Even though there are clearly aspirations for greatness, they're a niche group. There are others which already operate on the national and international/cultural level without the scrutiny scientology receives. I'd say they rank pretty low these days, knowledge of their tricks is prophylactic enough to bring them to a halt.
