The denial isn’t just on the part of Turkey. It’s a typical case of Muslims slaughtering Christians which is still going on in the world today. Saying anything less is just a way of allowing it to continue.
From Brothers Karamazov:
“These Turks took a pleasure in torturing children, too; cutting the unborn child from the mother’s womb, and tossing babies up in the air and catching them on the points of their bayonets before their mothers’ eyes. Doing it before the mothers’ eyes was what gave zest to the amusement. Here is another scene that I thought very interesting. Imagine a trembling mother with her baby in her arms, a circle of invading Turks around her. They’ve planned a diversion: they pet the baby, laugh to make it laugh. They succeed, the baby laughs. At that moment a Turk points a pistol four inches from the baby’s face. The baby laughs with glee, holds out its little hands to the pistol, and he pulls the trigger in the baby’s face and blows out its brains. Artistic, wasn’t it? By the way, Turks are particularly fond of sweet things, they say.”
