Scientologists have this museum right in the middle of Hollywood with zero indication that it has anything to do with Scientology until you have already gone in, given them your name and address and phone number, and been sat down with obvious handlers to watch a movie. An atheist social group I was a part of that coincidentally met at the restaurant next door every month decided to take a trip. Obviously, we all gave fake names and details.
Not only is the entire thing ludicrous (did you know that the Holocaust was caused by psychiatry?), you get to the end and there are a bunch of plaques telling you who their “special advisors” were, and you see the names of well-known experts on psychiatry- John Travolta, Isaac Hayes, etc. Surprisingly, no Tom Cruise.
