Can’t really say the will of the people is being ignored when referenda are planned, referenda which one can reasonably still presume will be binding.
I can see you can't really understand what a nationalist means despite one representative source I cited with regards to Mikis Theodorakis. I won't mock you for that -as you did- however to make my point easier for you here is a hint: M. Theodorakis has been a communist all his life and was imprisoned during the Greek dictatorship (Junta) in 1967-74. Junta is the 'dream' of Greek nationalists (see Golden Dawn). I think that'd be helpful
To my eyes Miki is reading someone else's opinions. Happens a lot lately. It looks like he is being used every time he steps up publicly regarding national matters. IMHO.
Nationalist Greeks are angry and so do nationalist Makedonians.
I would think both countries have more important things to protest about than name change, but then I don't live on Balkans.
