Maybe that Armenian was taught a biased history by the Turks about the Armenian genocide.
No, he wasn’t taught anything by Turks. Armenians are taught that Turks massacred them & Kurds joined in because Turks promised them something (land, maybe? I don’t remember). This was a betrayal, because Kurds & Armenians are both enemies of Turks.
I don’t know if it’s true or not, but this is what at least some Armenians have been told.
