Watertown boots ADL for refusing to use words "Armenian" and "genocide" in same sentence

Somebody tell me if I am wrong, but is the issue here that the ADL won't call the Armenian atrocities "genocide" because the Holocaust is considered a singular event and is considered to be the only "genocide" ever perpetrated? I have heard this before but wonder where the ADL stands on this. I would have to disagree with them if that is the case. Having said that, Armenian Americans seem to have developed an identity of victimhood around the terrible crimes committed against them by the Turks that drowns out all other aspects of their sense of culture and history. Are actual Armenians living in Armenia as obsessed about this? How healthy is it to allow the criminal to shape the image one presents for public consumption? This situation certainly makes Armenian Americans appear to be a little hysterical.
