Thank you T.A.M. This is what I was wondering about. I agree that 911 Truth appears to be quite different from other logically similar belief systems. Maybe I'm wrong there, that they are logically similar. Anyway, I can't shake the feeling that it is the content of 911 that seems 'interesting' and attractive to certain types of disturbed individuals. The idea of a body of knowledge created by and for a subculture whose members are disproportionately mentally ill is very strange. These are not institutionalized individuals and their knowledge is being used in an entrepreneurial way.
