Why would engineers be overrepresented among terrorists?My best guess would be that these groups are looking for people with the technical background to make and trigger bombs. There are other, pop psychology, explanations, but I'll spare you.

The report does remind me of Sayyid Qutb to American society in the late 1940s, which lead him to a write the book Milestones, one of the foundations of Salafism which calls for worldwide revolution and a new Caliphate. Most of the leaders of Islamist terrorist groups were influenced by Qutb's writings, which are totally at odds with any sort of religious tolerance..
