cornichon,
I don't know how often you got over to the Hollywood and Sunset area, but I frequently was around there when I belonged to the Hollywood/Wilshire YMCA. For shits and giggles, I actually went into a couple of the buildings, which I knew to be "fronts" for Scientology, like the "Psychiatry: An Industry of Death Museum" which was on Sunset just a couple of blocks from the YMCA.
It was creepy as hell as all/most of the people just gave off this vibe of the "true believer" who couldn't seem to engage in actual conversation, but seemed programmed to just follow a script by rote memory. The weird thing was, they would deny that they had anything to with Scientology, they were just trying to set the record straight about how harmful Psychiatrist were. Inevitably, any of those fronts would always try to get your name and contact info and typically, if you walked around that area of Sunset Blvd. between La Brea and where the main Scientology "Church" is located about a mile East, you could expect to get approached a few times to see a star-studded movie or a "free" E Meter reading. I could only imagine what they would do if they got a name, address and phone number from you.
Of course L. Ron Hubbard's fear of psychiatrist may have had something to do with the fact that smack dab in the middle of WWII, while he claimed he was out winning a chest full of medals by battling the Japanese serving in the US Navy, he was actually strapped to a bed in the psych ward at Pearl Harbor.
