They have lived under an oppressive government/governments all of their lives. There has been no freedoms or democracy in the middle east. To qwell rebellion their governments have allowed, funded, supported madrasas to fuel radical fundamentalism. As long as that hatred could be focused on the Jews, the Christians, the West, etc it kept the focus off of their own repressive regimes. They aren't "born" that way but those of the Wajabi sect are indoctrinated that way from birth. There are successful, democratic Muslim countries (Turkey) who don't export terrorism because they give their citizens a chance at freedom. The Saudi citizens barely work. They import muslims from other repressive countries to do the menial duties. They find each other and fan the flames. You need to be realistic about the what we are actually up against.
