Right...and according to some around here Christianity isn't either. Too many people either don't have dictionaries or don't know how to use them. Christianity and Islam both fit the definition of a religion. They also fit the definition of hallucination, wishful thinking and fantasy. Regardless of how members of those groups try to redefine themselves, their belief in fictional superbeings and their determination to make everyone else believe as they do (by employing propaganda, appealing to emotion or threat of violence) marks them as religions to those of us on the outside.
