Flat Earth people

I finally figured out the reason they persist and spread.
Flat Earthists emit refined 'blind faith' and strong emotions when their beliefs are challenged. Both of these are forms of loosh(aka lulz,emotional energy) to feed trans-dimensional aliens that secretly control all bio-life on Earth. Deeply Religious beliefs are persisting the same way: Flat Earth is a new religion for a more secular society.
