Then you could probably say the nationalist Hitler riled up the Christian masses to help him carry out the mass killings of Jews. Hitler must have looked to Talat Pasha when formulating his Final Solution.
That there was some ingrained hatred is undeniable, but the Muslim authorities were happy to keep the Armenians as second-class citizens, and only murder them when they got out of place. It took the secular Young Turks to turn it into genocide in a nationalist fervor (they claimed the Armenians were pro-Russian subverts).
Actually, you are dead on about Hitler. His cronies told him he couldn't possibly pull of something on the scale of the Holocaust, to which he replied: "Who today remembers the Armenians?" And yes, the Ottomans did claim that Armenians had been joining invading Russian forces - plus, with all their other Christian holdings breaking free of the Empire they were going to stop Armenians from doing the same.
