Tribalism is based on blood ties between member of a group. This has nothing to do with nationalism which is the most evoluted social structure where blood ties where replaced by common morales, culture and languages. Tribalism is a very low form of social structure, highly linked to our primal condition of mammal individual. Nationalism and sovereignety are far more advanced social structure in an attempt to extract ourself of our natural condition. Modern society based on compound of different community, and political communautarism are just a major fallback to our primary mammale condition and an systematic attempt to destroy superior form of social structure. And i would not much trust the thinking of a proselyte member of one of the most tribalistic social group on earth, expressing his opinion about universal society, due to the fact that his mind has from birth a tribalistic biais.
