Re. the OP.
Many of the world's religions are based on people claiming that their god appeared/spoke to them. Judaism, Xianity (Paul), Islam, Mormons (Smith) and JWs (Russell) and others.
'Distance lends enchantment' - or, in other words, leave it long enough and the passage of time will blunt, obscure or forgive the obvious (to our modern minds) craziness.
Ask yourself this - if Joseph Smith or Charles Taze Russell was around today and spouting their nonsense how successful would they be?
(Yes, I know you could cite Hubbard and Scientology but there will always be some crazies off the scale).
