I should say that the handlers were so ridiculously obvious. They were pretending to be tourists who just happened to already be there when we already showed up and they watched us the entire time. I have no idea why they thought that would help sell their museum.
But if I remember correctly, Scientology or Hubbard were never overtly mentioned, or if they were, it was hidden amongst the large volumes of text in the museum. It was clear right away from the language that it was all Scientology, but if you weren't familiar with them, you might not know.
That said, Scientologists are all over other parts of L.A. including Hollywood offering "free personality tests," so they probably don't need people to know about that particular arm of their church being related to them or their crazy ideas.
