Boris on British Jihadis. Apparently based on MI5 intel:

“If you look at all the psychological profiling about bombers, they typically will look at porn. They are literally w***ers. Severe onanists. They are tortured. They will be very badly adjusted in their relations with women, and that is a symptom of their feeling of being failures and that the world is against them. They are not making it with girls, and so they turn to other forms of spiritual comfort — which of course is no comfort.”
