7) GREEK CLAIM: "Macedonians celebrated the same festivals as the rest of the Greeks. Examples of festivals which were celebrated in Macedonia as well as in other Greek states are the "Hetaireidia", the "Apellaia" and many more."

This is not a proof that the Macedonians were Greek. How many festivals (Christian, Buddhist, Islamic, etc) are today being shared by many ethnically different nations? Are we supposed to say that since the Portuguese and the French Catholics observe same traditions and religious festivals, they are of a single Portuguese or French or whatever ethnic origin? Of course not, the modern Greek argument is fruitless. This is a proof that even if the Macedonians and Greek have shared certain customs (like many other nations can do today as in the past, especially bordering nations), that in itself is not a proof that those Macedonians were Greek, just like the Portuguese are not French, and vise versa.
