Terrorist Muslims come from authoritarian, sex-negative families that have been destroyed by the social upheaval that is happening in Middle Eastern countries. Early in their psychosexual development, these youngsters are educated to not feel (to repress) their natural sexual urges. As a result, their pleasurable feelings become twisted, distorted and experienced as something evil. During puberty and adolescence, their feelings intensify and, for some, become intolerable.
These young people are raw material that become indoctrinated and recruited into the jihadist movement by Islamic ideologues. The intolerance that they have for people enjoying themselves is a projection of their own suppressed sexual feelings. It is combined with a mystical loyalty to their fanatic leader that directs them to do Allah’s bidding, turning them into a weapon of mass destruction. Blowing people and themselves up is the sadomasochistic solution associated with an emotional (sexual) release through an act of physical bursting that they have been trained to long for.
