Guys, look up the real definition of a cult. You have to meet certain criteria that not all organized religions meet.
And, I don't care if you believe in Scientology. What I do care about is that, if you oppose it, you are hunted down by lawyers and others who dig up personal information and use it against you until you either drop what you're doing or are driven underground (some notable Scientology critics have even been jailed), if you want to leave the "religion," you are sent to what is basically a gulag and "reeducated," and your family completely disowns you, which is a policy set by Hubbard himself (you may argue that the Catholic Church had a similar policy in the middle ages, but that wasn't set by Jesus.). Also, you are given education under the guise of learning more about Scientology, which does not meet even minimal educational standards. Finally, you are forced to pay money to progress in the CoS. Yes, most religions have or even require donations, but you don't have to pay money just to learn more about what your beliefs actually entail.
I also find their views on psychiatry rather frightening. I could also mention the extremely dubious Dianetics, but I won't open that can of worms.
As for a lawsuit, the protesters are probably purposefully concealing their identity because most Scientology critics have to keep a low profile.
Jimmy, what are you doing here in the middle of the night? It's almost 9 PM!
