Of course. Alexander did recognize his soldiers as Macedonian, but HOW ?? What did he do to be sure about them?
The word Greek is the name of a (Greek) tribe that lived in Dodona, Epirus, during Deucalion's cataclysm (10.000 BC) Aristoteles wrote. Those Greeks are the first Greek tribe that Roamns got in touch.
No Roman ever separated southen Greeks and Macedonians BUT geographically.
We have hellenized all those peoples (including Slavs) who you say they came in Greece. Due to the attractiveness of our Civilization. Instead you have been slavicized, mainly because your civilization was worst than Slavic one.
We have also "hellenized" Turkish blood by paidomazoma (massive kiddnapping). About 500,000 Greek pupils' blood is now in Turkish veins.
Blood and DNA are not related to ethnicity. If I adopt any SlavoSkopian pupils I will make them proud Macedonians like me. We are what we have been taught to be. That's why you think you are "Macedonian". Tito ordered you to be and you loved it very much. Otherwise you would be un-famous west bulgarians.
We are Greeks not because of our blood, but because we have Greek names, toponyms, ways, heroes, (gods) dialect and we are proud of that campaign that Macedonians did to spread Greek Language and Civilization to the World.
But you didn't tell me, how do you SlavoSkopians recognize each otehr as SlavoSkopian????????????
Macedonian, therefore Greek
