What this unfortunate man wants to say is that if a country in Northern Europe calls itself Aztecland, they can claim their history, culture, national and local identity of the Aztecs, since there is no "taken" Aztec nationality at the moment nor is there any "official" document of an Aztec land linking the Aztecs with the American Indians of these lands today...  

 You cannot have an Aztec nationality in Mexico, since the nationality of the inhabitants is Mexican... There is no Roman nationality in Italy nor a Visigoth nationality in Morrocco or a Celtiberian nationality in Spain... What you are asking makes NO SENSE.... If you just want ANY formal paper mentioning the name "Macedonia" or the adjective "Macedonian" referring to Greeks this is also too easy. There are thousands of official Greek papers (since of course the formation of the Greek Republic) which mention these words. Is it "official" enough for you the Treaty between Philip V and the Carthaginian Senate which clearly links Greeks and Macedonians? Anythging written by ancient historians you would call "history books", thus not official... Are maps, military, state and commercial "official" enough (of course you cannot believe the absurdity that the Greek maps did not include the name "Macedonia" before the formation of FYROM????)? Is the celebrating of the "Macedonian Struggle" (the struggle of Greeks to liberate Greek Macedonia) nationwide "official" enough? Will censuses and voting lists clearly using the name of "Macedonia" to denote the said Greek region "official" enough? What are you getting at? Do you really believe that Macedonia was some kind of a taboo word? Please get over the insane and absurd propaganda and start a real debate...
