Yosser,
A few years ago the priest of my former parish and his wife went on a cruise to Constantinople and the Black Sea. During the Byzantine times there was a monastery called Stoudios which was basically like the Yankee Stadium or Wrigley Field of Orthodox monasticism. Today, it is a ruin that is fenced off and overgrown with a Turkish Army soldier guarding the place to keep people out.
My priest and his wife, after a two hour cab ride, were able to find the place. They went inside of what ruins are left and were kicked out when they ran into the guard. The guard was yelling at them and a crowd of onlookers quickly formed. An Armenian, who could tell they were American and if in that area clearly Orthodox, went up to my priest and his wife saying, "A cab will be here in two minutes. You will get into the cab. You will not return here because if you do than life will be difficult for the Christians in this neighborhood".
That is an example of the xenophobia that is modern Turkey.
Now, ethnically speaking the other posters here are correct: The real Turks are in the part of the world we call Central Asia or "The Stans" because of Kazakhstan, Uzbekistan, etc. Those people are the real Turks. The "Turks" of Turkey are ethnically the descendents of mostly Greeks, Armenians and Kurds. There language, however, is from Central Asia.
Something of note about the people of the Eastern Mediterranean: religion and identity go hand in hand. It is a foreign idea there to be, say, Armenian and not Orthodox just like it is a foreign idea here in the States to be, say, from Utah and not Mormon. Most of today's "Turks" in Turkey are descendants from Greeks, Armenians and Assyrians who call themselves Turkish, became Muslim and adopted the language so that they could not pay a few hundred extra bucks in taxes and not be killed when the fanatical Turks come knocking on the door.
That being said, there was a few years ago, a quasi-celebration in Trabzon of Turks who were celebrating the Greek culture that was in Trabzon until the 1920s. Turks who were descendents of Greeks actually wore lapel pins and ties that had Byzantine eagles on them. The celebration went on for an hour and a half until people started singing in Greek and shouting Greek Orthodox phrases like "Christ have mercy!" and it was then quickly shut down.
I will tell you something right now: Turkey will never join the EU because Turkey will never truly adopt the human rights demanded of her by the EU. I do believe one thing though; the day Turkey adopts, implements and allows basic human rights for all of the people in Turkey will be the day when we will see millions begin their return to Orthodoxy.
