I feel slightly differently in that I think a lot of people are so horrified by what is going on, they want to use a word to describe it that conveys the horror/suffering/pain. I’m stealing the words of Sands KC but there’s a cultural definition of genocide that links with something we should never let happen again. To be clear, I’m not comparing it the Holocaust. I’m just using that phrasing in its basic sense.
Similarly, when I describe the atrocities on 7/10, I often pause to work out what adjective/noun is suitable to capture what happened that day and I think the same is true for the suffering now in Gaza - people want to stress how horrific it is and genocide is a culturally a word that people feel fits the actions and rhetoric of the Israel govt.
I think it’s good to keep in mind that SA have brought a case to the ICJ and it is a very real possibility that Israel will be found guilty. Wiping Gaza out on 8/10 would’ve made it an easy case, doing it over a prolonged period with the cover of war is less easy to try but still as disgusting.
Like you, I hope it comes to an end soon and the crimes committed (war crimes/crimes against humanity/genocide) by nay involved party are recognised.
