"We are our beliefs," it is said. Beliefs steer people in life. Some beliefs are harmless, some are the motive force for good, and yet others are delusional, misguided, and even outright dangerous. Every version of the belief called "Islam" ranges from the delusional to the dangerous.
Islam is a Grand Hallucination, birthed by Muhammad's hallucination that he relayed to his first wife and employer, Khadija. Greatly frightened, he told Khadija that he was visited bya jinn (devil) in the Hira cave. Khadija comforted the distraught man by assuring him that the episode was Allah's way of choosing him as his messenger. Muhammad believed his rich wife-employer who was 15 years his senior and the hallucination became a belief -- Islam.
Remarkably enough, under the early tutelage of Khadija, Muhammad succeeded in attracting a number of influential followers. Before long, the movement gathered more and more power through violent campaigns and the faith was taken to new people and alien lands. This grand hallucination, Islam, presently has in its stranglehold over a billion humans, posing an existential threat to all non-Muslims.
