I actually don't. Would love to see a few sources which gave you this insight. I'm keen to see what kind of education they have.Actually you do know most of the terrorists are highly educated people.
When I say educate, that necessarily doesn't always mean a Bachelors/Masters/Doctorate though having that kind of formal education increases the chances of someone being actually educated.I mean what's the point of so much education when someone can make them go astray within a month of brainwashing.
I know brainwashing is a dramatic word but it is a form of biased unfair education.
If you're constantly fed videostreams of atrocities in Syria, Iraq, Kashmir, Palestine, Burma, Libya and by association linked everything to "America/Israel Conspiracy AGAINST ISLAM" coupled with a few dumb-ass speeches by people like Bush Jr and Trump and so on and then asked the question as to why media doesn't cover this side of the story? You know, stir the emotions and hate and fuel the jazbati jehadi in the "Muslims". The process called "Radicalization". It can work on anyone who's emotional and considers themselves on the "same side" as the victims of atrocities. Who might hold a BS or MS in engineering or medical but not necessarily in history or economics or politics or business.
When I say educated, I mean mature enough to realize the although Islam may be perfect, but its execution and implementation started showing cracks as early as late first century Hijri. There have ALWAYS been "hidden third parties" in the world during any time which have benefited greatly in business and money making by conspirating against governments and causing conflict. Those who own the bullets and bandages or interested in the share of booty, who don't give a rat's ass about ideology.
