"Your folks were caught cooperating with the Bulgarians during the WWII (Caltcheffs' infamous Ohrana), who were in turn collaborators of the NAZIs (Greece was divided between Bulgaria, Italy and Germany during WWII)

After the WWII your folks transformed overnight from Fascist collaborators into Communists (!?!) but they were eventually expelled from Greece along with many other Communists by the end of the Greek civil war.

In the end, your folks are barred from returning because the expulsion of all of the populations that were accused of collaboration with the NAZI regimes and collaborators has been permanent in all cases, whether this is Chechoslovakia (Benes decrees), Poland, (a portion of Germany was ceded to Poland forever) Finland (which lost a portion of its' territory to Russia) e.t.c.

Below you can find a quote by your own Andrew Rossos (one of your refugees turned historian in Canada) who half-heartedly admits your collaboration with the Italian, German and Bulgarian occupation authorities, and Vancho Mihailovs' IMRO (IMRO has been a terrorist organization responsible for the assassinations of the Bulgarian prime minister Aleksandar Stamboliyski at 1923 and king Alexander of Yugoslavia and French foreign minister Louis Barthou at 1934).

"In Macedonia, however, the KKE and EAM-ELAS faced stiff competition for the allegiance of the Macedonians...
...Many responded instead to the calls of the Italian, German, and Bulgarian occupation authorities and of Vanco Mihailov’s Internal Macedonian Revolutionary Organization (IMRO), who promised them liberation from Greek rule in the form of a “free,” “autonomous” “independent” or “united” Macedonian state..."

If your own propaganda proves you NAZI collaborators... even a little bit.."

"So you admit that you killed your own prime minister because some minority (IMRO) didn't approve his policies, right? What about the majority who voted for Stamboliyski? Were they traitors as well?

Anyway, it is pointless to discuss this issue since you cannot provide that the people whom you consider as Bulgarian actually felt Bulgarians. Some of the greatest leaders of the IMRO were Vlachs (and therefore not Bulgarians) like Pitu Guli. Those fellas preferred a Switzerland-like Macedonia rather than a Greater Bulgaria and IMRO's stance was ambivalent on the issue, until it was split to those who promoted the Bulgarian ideal against those who preferred a Macedonian state composed of Bulgarians, Greeks, Turks, Jews, Vlachs e.t.c. In the end, some were fooled to think that they are Macedonians of the Ancient breed!!!

You have to wake up and - much like your forefathers - realize some day that very few of those "Bulgarians" wished to be citizens of Bulgaria, and they realized that those without a national consciousness required some coercion to this end. This coercion was frequently violent - like the execution of patriarchist priests - and this violence turned the Greek state against you. Your mistake was the abandonment of the peaceful effort (education) and the adoption of violent solution against not only the Muslims, but also your fellow Christians. This was simply impossible, and all the Russian support in the world was not enough to help your cause.

The massacres and the expulsions of the populations of the former Ottoman empire are a very common sight in the modern Balkans, even as recently as the Yugoslav tragedy of the 1990's. The rise of nationalism out of a world that defined itself out of religious convictions for two millenia was an inevitable conclusion. Still, you cannot claim that you suffered more than the Armenians (1.5 m dead) or the Greeks (1.5 m expelled + >0.5 m dead)..."
