States, in any case are bullies. They bully communities into accepting the rule of law of a governing centralised elite. Just because different communities with different cultures, languages and identities live within set geographical borders they may have different values and interests. Civic nationalism and modern states dictate that they all have to tow the line. This is why National Anarchists ARE anarchists! We believe that people should be free to choose their own identities and live (within reason) by the own values and systems - within their own separate, self-governing tribal communities.
The sectarianism we are witnessing in Egypt and Syria can surely be addressed by the concept of National Personal Autonomy and the curtailing of state power in favour of tribal autonomy and decision making - and of course with the development of tribal economies too.
