I've a good friend who is a Berber from Algeria. He certainly has not been conditioned by islam and holds a great deal of disdain for his arab neighbors. He also expresses worry for his family because they are in constant danger of violence from islamic extremists. Unlike him, the members of his family in Algeria are devout muslims. They're also very open people and curious about other people, including non muslims. It seems that their more radical neighbors feel that they're not 'extreme' enough.
