Shame on you.
Why must people pretend they're so enlightened when they're nothing but sheep. Using nothing but tunnel vision to analyze and reach ridiculous conclusions. Take a long hard look at yourself and your own so called superior and modern world before judging others and others beliefs.
There's consequence to everything. Decades and centuries of meddling with other peoples affairs, stealing their natural resources, deposing and placing ruthless dictators whose crimes have and continue to go unnoticed, supporting proxy wars, etc. etc. all these things have a domino effect. You can refuse to admit it but history speaks for itself, the monsters that exist today, their seeds were laid with the help of many hands both in the East and the West. Now they're coming to bite the hand that fed them. Let's try to remember what triggered the War on Terror, a certain man by the name of Osama bin Laden, an ex-ally, who with the support and funding of the CIA brainwashed several generations of aimless men who were then discarded and left to do as they wished. I wonder what the world would look like if Afghanistan had been offered something like the Marshall plan? Maybe then the Taliban, perhaps the first modern offspring of the "Mujahideen" (labelled as Freedom Fighters by the politicians and the media aka the sheep herders) wouldn't have existed or found a suitable environment in which to cultivate. Maybe then there wouldn't be millions of Afghan refugees with all their baggage the world had to deal with it.
Now just go country by country, look at its history over the past century and ask yourself, is it really "Islamic" extremism you're fighting? Or is that simply the facade? Are 1.5 billion people truly all of a sudden bat shit crazy and want to return the world to the middle ages?

Ffs, open a book.
PS: This post was made possible through the extraction of Coltan, a rare/hard to come by metal ore, found in very modern and advanced countries like Rwanda, Uganda, and the Congo. No civil wars or deaths were caused in the extraction of coltan because such an accusation against liberal peace loving countries would be absolutely insane. Only Muslims like to fight and kill each other...it's in their literature, everyone knows that. Our constitution is all about smoking that peace pipe and spreading the love yo. Thanks for reading.
