Thanks for posting this as its own thread.
Stay well - stay safe - stay armed - Yorktown
The killings and expulsions really didn't kick into high gear until the modern, secular, Turkish state was created after WWI. And it's really more ethnic than religious...more anti-Greek than anti-Christian.
Another thing to keep in mind is that the Greeks tried to take advantage of the collapse of the Ottoman Empire at the end of WWI by invading and trying to take over the entire Western half of Asiatic Turkey..not just the part in Europe. There were horrible mass atrocities committed by BOTH sides in that war. Ataturk finally rebuilt the Turkish military and drove the Greeks out.
Donning flame-retardant suit against the FR pro-Greek contingent now :-) I don't particularly have a bias, just pointing out some salient facts. I'm neither Turkish nor a Muslim. :-)
