Alexander does not have anything in common with modern Macedonians, we don't know exactly were the ancient Macedonians Greeks or not ( I think yes) but the fact that cannot be taken out of consideration is that he – Alex was one of the biggest admirer of the Hellenic culture.
Modern Macedonians are Slavic people who are gigantically similar to Bulgarians, their culture is Slavic and byzantine. I don't know how much time will pass before some guys will stop to spread nonsense about Slavic character of every people which pre-dated modern Slavic nations. Illyrians, Thracians, Macedonian Greeks etc. were not Slavs, Slavs came here 15 centuries ago and there is nothing shameful about that.
