An excellent point and well put! I hadn't considered the juxtaposition of 'celebrity' and 'scientology' in this way. You're right, it's quite radical and obviously a stark contrast to 'mainstream' religion.
Their ways are so matter-of-fact to us now, we forget just how radical they are. Tailoring a religion specifically to appeal to the most narcissistic element of society, even building them a special Celebrity Center, providing them with self-centered existence where every need is catered to, is a radical exercise for a supposed religion.
Even more radical yet, is sacrificing the career of the world’s biggest movie star on a Global War on Psychiatry, because a dead science fiction once said that psychiatrists are reincarnated goons of the evil intergalactic warlord Xenu.
It's a sick situation, but the way you describe it is funny as heck!
There are barely any Scientologists at all. But it’s their willingness to engage in behaviors so radical, based on such horrifying and dangerous idiocy, that gives them a visibility far beyond their numbers.
Frankly, I wouldn't be surprised to discover there are fewer than 10,000 active scientologists. But 10,000 or 50,000 that is, as you say, "barely any scientologists at all". And way out of proportion to the attention they receive.
