Because screaming genocide at everything detracts from the credibility of the person doing the screaming.

In the last 10 or so years the conflict has cost about 4000 Armenian lives and 3000 Azerbaijani lives. For comparison, Russia loses that many troops in a week in Ukraine, inflicting similar casualties on the Ukrainian side. Most of these, by the way, were troops.

It would be silly to call this genocide. If you did, is 9/11 genocide? Similar losses by numbers and all civilians, so why not, right?

You see this with the Israeli Palestinian issue. People talk about "slow motion" genocide because they can't defend the actual genocide accusation either.

For it to be genocide you have to demonstrate someone is trying to wipe out a group of people or a portion of it. What happened to the yazidis with Isis was genocide. What happened in the 20th century in Armenia was genocide. What happened between the tutus and the hutsis was genocide. If we throw in every conflict where 4000 soldiers die and call that a genocide too, we devalue the term - same as calling every teacher you dislike a nazi.

I suspect Armenia, of all countries, knows what a genocide is and how it happens. They're not looking to devalue something they're still fighting to have recognized.
