You say it is racial. Yet christian sand people, from Syria or Lebanon, absolutely don't behave this way, and behave more like westerners, despite being sand people as well. What is responsible for this behavior is Coranism culture, which incite violence against non muslim (Jihad, killing the infidels). And also razzia culture, which comes from muslim based country. Now Vikings also had razzia culture, but it was a very long time ago, and it's long forgotten by the Scandinavian people. Arabs, on the other hand, had their ancestors practizing razzia just a few generation ago. Yes they are archaic savages. And yes they will be put in check. But not the way you think they will.
