I really don't like to pick such hooks, seems that the author tries to act as a vulture facing a drama, but watching the video of the terrorist striker on Norway and getting some hooks on social networks, hackers, and social network owners character, maybe who is behind is such thing called 'predictors and what he was looking all time on WEB'. That thing dragging the individual to some sort of mental crusade. I can infer several things about the author, he is probably lacks on abstraction, 'pure abstraction', that thing to walk around and let your mind safe on the 'abstraction zone'.
Second probably he noticed the cultural shift to have neighbors or relatives that don't drink beer, don't like jokes, and believe that 'life after death' will have some sort of 'meritocracy of the present obligations'. Also an enormous lack of 'knowledge' on marxism and the science of speech, see that Marx ideas were poisoned by the soviets, nasty people, haven't fixed yet latitude authentication. Also, take an example of his mixed up of historical facts without too much judgement on 'why they went there?'.
What was the purpose of the "Crusades?", the caravans, were a source of giant profit for all kind of commerce at that time, usually such caravans moved millions of individuals, just like we saw on Islamic World, the travel to Meca, such things at that time were the first signs of multicultural plurality on world. You are not obligate to like, for example, meat, barbecue, beer, smoke, veganism, yoga, you are not obligate to like, who said that for example yoga don't cause damage on bones? We know that Olimpic Gymnastics, swimmers and other sports causes a stress on individual body that after some years he felt the effect, gain of weight, problems on joints, if not worst like damages on areas of the body that don't have a mechanism of regeneration, like brain, eyes, pretty sad.
The second motive of such Crusades, prestige, the individual sleep well when he is in a crusade even by the wrong motives, like for example, why you should not consider Microsoft Products during an architectural proposal? Simple, QOS, too much defects, AKA virus, trojans, then the code is not open source, probably have like lines of code from Compaq by 20years ago, 'don't touch is working'. Anyhow we cannot avoid to deal with Microsofters, they are spread around the world, like a cancer, that thing remains there, a little cancer looking for prestige again, kill his own friends on some sort futuristic adventure, we cannot deny 'pretty odd individuals'.
So, we have economical motivation and prestige, with whom? Simple, at that time nobody had internet, games or television, so first with the peasant, second with the Pope (aka the banker or stakeholder), if you gain the grace of the Pope you are a lucky man, so this was the real motivation, also at that time they were totally compelled to believe on life after death, do you have any idea why? No tooth brushes for the wives, have you imagined kissing a 'lady' that don't like to take a shower, neither a basic tooth brush, and moreover with rats in head, pretty nice hum? So, lack of things todo, no web, bad breath women, "let's go to the war".
