How about:
Turks took the two oldest male children of the faily and shot them right in front of their parents eyes. They then raped the daughters in front of everyone else, shot them too, and then smashed the grandmother's head between two rocks. They then mopped up everyone else.
The difference is America is in a war. They don't care what specific race dies, but in the Ottoman empire it was a specific type of people. The Armenians were not at war with the Ottoman empire, and anyway the Ottomans didn't have planes so that they couldn't really see what they were killing, they had to go in and do it close up. Unlike a bomber, they can see what they are killing.
