OT: Insight into individual and cultural factors in Islamic terrorism, the role of sexual repression

What drives  many conservative Muslims into unspeakably brutal terrorism? What drives even some westernized Muslims into this horror? This NYT story is about a relatively educated and affluent young conservative Muslim male who felt guilty about his "western lifestyle" and joined ISIS.  Unlike many other analyses,  it offers some relatively unexplored insights on both the individual and group level.
"There is no single path that leads to jihad, but in exploring Mr. Yaken’s life, signposts emerge. There are influences familiar and easy to discuss, like a lack of economic opportunity and a renewed sense of political alienation, especially among youths. But there are also more delicate subjects — less often publicly debated, let alone dissected — like the increasingly conservative thinking that defines the faith for many Muslims today, or sexual repression among young people who are taught that their physical and emotional desires can bring them eternal damnation."

"This conundrum, often presented as a choice between a modern Western lifestyle and living a pious life, is central to understanding how Mr. Yaken transformed from an ambitious bodybuilder who tried to cast his charm on women to a jihadist violently imposing the strictest social code."

Conservative Islam with its strict rules on sex causes both sexual repression and sexual guilt. Going to the repressive extreme seems to be one possible way to deal with these feeling.  On the group level, the permissiveness about sex, nudity and pornography of western culture which is a message available to all on the internet, is a serious threat to conservative Islam.  Many have the unpleasant emotion of both being tempted and hated by the temptations of western culture.  Violent reactions are one way to deal with these uncomfortable, conflicting emotions.   Perhaps it offers a distraction that is strong enough to overcome the issues. They secretly envy the West, but hate it.  Perhaps the answer lies somewhere in the theory of cognitive dissonance.
