It is amusing to see those trapped in extreme HAAD, the source and whole content of religious illusion, pretend that it is their opponents who are in a state of religious fantasia.
(Of course questions like "whyever do people believe in gods?" will feel less like questions that need such answers to those who themselves believe in gods, because "duh, because there actually are such beings and sometimes people interact with them and sometimes we notice that" is a good answer if its premise is true.)
