Surely there's a scale?
Technically, any "killing a member of a group" would be a genocide under this definition.
Even if someone commits a mass murder against a group, we typically call it mass murder or a hate crime -- not genocide.
So there has to be some idea of what genocide is -- what is the scale, what is the intent? Is it to wipe out a people? Or is it something else?
25,000 death is a lot. I'd say its a war crime. An atrocity, perhaps. But a genocide? Against a population of 2 million? Idk. Maybe?
It seems that we have no common definition of the word
