Rolling Stone provides a typical faux-analysis that makes excuses and doesn't address real causes for the allure of Islamic fundamentalism to creatures like the Boston Bombers. To trace out all the tortured paths pulling people not born into it into a nihilistic religion of mass psychosis would require a book, but fundamentally, the appeal of Islam is to those who seek power over others.
Why power? Because the people Islam attracts are neurotically (and in many cases, psychotically) self-doubting and self-loathing.
Power over others is a path to pseudo-self-esteem -- the illusion that they are better, more able, more worthy of living because they can control others, inspire fear in them, kill them, enslave them. More powerful.
This compensates for an intense, and usually well-earned metaphysical inadequacy -- an Islamist or wannabe is at root unfit to live in reality, a congenital incompetent.
At some level, they know it: it is to this psychological substrate of individual self-loathing that the sophistry of cultural self-loathing makes its appeal -- offering the Islamist candidate the opportunity to wallow in all the flaws alleged or real of the Western society he lives in, without any balance of all the immense good of Western culture over all others, giving him the convenient scapegoat of a bunch of amoral sinners for all his personal problems -- provided on a poison-coated silver platter by the post-modern cult of phony toleration and illusory coexistence.
This is what breeds monsters operating under the veneer of the "religion of peace" -- in the West, at least.
There are deeper causes, layers and layers of them. Most fundamental of all are generations of intellectuals -- especially philosophers and theologians -- who concocted massive rationalizations for even more massively irrational ideas -- the insignificance of the individual in existence, or the inefficacy of his mind to help in his struggle to exist, via schools that poison his mind with that irrationality and much more, brainwashing him to follow twisted paths of convoluted pseudo-reasoning, and leaving only knots of confusion, inadequacy, self-doubt, chronic fear and frustration whenever he gropes to think, a metastatic twine ball made of the detonation cord of hatred for anyone and anything he sees as the scapegoats for his tortured efforts to think.
Out of such Frankensteinian bits and pieces do you stitch together a mindless killer and a destroyer.
And then there is Islam, in the shadows, whispering that he's right -- that all his fears are someone else's fault, and offering him the moral rectitude and the power and the reward of 72 virgins in an alternate reality to put things right with a bomb or a gun or an airplane.
The same psychological process of corruption takes place with Marxism, with this interesting variant: where Islam appeals to those who want to shut off their minds, communists (the most dangerous variant of Marxist) appeals to those with megalomaniacal tendencies of alleged superior intelligence -- a different rationalization for the same root disease: feelings of metaphysical incompetence, and the same object: the desire to rule and destroy to prove otherwise.
Except the committed Marxist who believes he is smarter than anyone else aims to achieve rule using somewhat different means -- ie, faux-intellectuality and twisted conspiracies.
The end is the same though: absolute rule and death and destruction.
Then we come to Barack Obama -- a communist and a promoter of Islam. QED.
