I'll just chime in to mention that Bendy Light is not believed by many Flat Earthers. It seems to me to be an invented fantasy, and it violates occam's razor: there is no phenomenon which is not better or equally well explained in far simpler terms, such as by the natural perspective conventions laid down by Rowbotham (the father of modern science), and taking into account the proper distances of the heavenly bodies.
However, I am respectful of my colleagues who hold these beliefs.
