It's about avoiding useless acts of anger. Why hating peaceful population of a certain faith ? what will this do ? I just saw a documentary about day to day "life" in Iraq, these people are just like me and you, victims. Victims of what ? that's the question. Some are fanatics, some are clinical psychopath that want to kill, some are gullible lost souls believing in evil/good and rallying ISIS thinking it's the good (lots of westerners), etc etc Now include the hidden political ties behind all this, because we ~know all States have helped to trigger the fever since the last 40 years (ISIS gets money selling oil, who buys it ? weapons from other States, including past help from westerners, who keeps helping them growing aggression power ?). Now answer this ? what is "the" cause ? how to stop it without creating more problems ?

So far nobody really knows, nobody talks about viable solutions except typical PR/Medias speeches. It seems a really nasty mess involving lots of nations, populations, ethnic and religious groups.
