The so-called "Arab world" is also just a fiction of the 'secularists' and 'nationalists' that you oppose, so why do you talk in terms of an 'Arab world' being 'this and that' ? In reality there isnt really an 'Arab world' unless you are a pan-Arab nationalist. Arabic-speaking countries dont share the same peoples, conditions, histories, cultures, traditions or even 'Arabic' language. Their mentalities, needs, pasts and presents differ massively from each other and will never be the same and never have been.
Talking in terms of an 'Arab world' makes you one of two things: 1) a secular Arab nationalist or 2) an Orientalist.
You claim to be neither, but your thinking is clearly influenced by both.
