The ethnic Macedonians only have one autonym - Macedonian. They don't want to piss off the Greeks. The use of the term to refer to themselves and their language is not an attack on Greeks. If it were, they would use the autonym "Greek" not "Macedonian". And "Aegean Macedonia" is not necessarily an irredentist term. It can be used as such, but it is also used just to refer to Macedonia, Greece. You use the term "Greek Macedonia" which is considered offensive by ethnic Macedonians because it suggests that that area is Hellenic, as opposed to only being under the control/jurisdiction of the Greek government. And then comes the dispute about whether Macedonia, Greece is Hellenic or not. 

Either way, if you don't want to be labelled nationalist or don't want to offend either side, I propose we use the terms "Red team" and "Blue team" to refer to the two groups of Macedonians - based on the  two flags using the Vergina sun. Alex 202.10.89.28
