The flat earth society consists of just a handful of individuals, as far as I know. I should probably clarify two more points:

1. I'm looking for beliefs with a relatively big amount of followers. Individuals believing absurd things noone else believes seems like a case for men in white coats to me. When a substantial number of people share a belief, however, we are faced with two choices: the number of people diagnosed with mental disorders need to be heavily cranked up OR it is possible to explain such views in ways other than insanity. For this thread, I'm going with the assumption that the latter is true.

2. I included Eurabia and related theories. They are certainly absurd, but I wouldn't say that they are as absurd as September Clues. A no plane at all theory is a step up the absurdity ladder than saying Mossad drove the plane, to give an example. Still, there may be some common ground between the two, so I'm happy if someone has something to add here.
