The definition is offensive, perhaps it is suppose to be, but a simple statement stating that characters will react negatively in game because gods do exist. Instead it is a paragraph from some religious npc.
How can a player be offended by a fictional religious character in a fictional religion?
Yes, PS definitions can bring confusion. Yet, for what I remember of character creation, it wasn't atheism that confused me: it was stated that atheists are insane, and I simply took it as game fact. What I found myself at odds with is that I wanted to be a polytheist, or undecided, or whatever they would call it if backed with a proper description.
It doesn't matter if PS atheists are actually insane or not, if they are right or wrong, if gods are gods or something else powerful enough to play gods, if people see only what they choose to see, etc. Settings are debatable in game, because characters don't know they are settings, they don't know what the players (think they) know. To me, the real confusion is that the distinction between belief and worship is not clearly made. In that regard, we have a definition for a rare case (disbelief), and not much for what usually makes the majority in a pantheon case, i.e., worship all loosely and let priests do the specific worships.
