To me, the concept that the Cold War (and all wars back from that, until whenever the conspiracy espoused began) were fakes to keep the peons under control is the dividing line between CTs who are sane, if misguided, and those who are desperately delusional.
It's one thing to suspect that the moon landings might be hoaxed, particularly if you've only read one side of the story. To firmly believe all reality is a hoax is a different mentality entirely.
