It's frankly unclear to me that there is. The definition of genocide seems to have expanded from its historical roots, and I haven't seen the pro-Palestinian faction in America make a credible claim that Israel is fighting this war materially differently from how every other war has been fought in the past decades by each of the U.S., Russia and China. I think the war should stop. But because war is horrible, not because it's in a special moral bucket.
But! I haven't done extensive research on this. So I'm really not claiming to know one way or another, just that I've put the whole thing into the same bucket as the Uyghurs, Sudan, Eritrea, North Korea and the other horrific places on the planet that I don't have much control over.
> calling it your “pet” war shows you aren’t serious
I mean, yes. I'm also about as serious about it as these folks were. Namely, I haven't had much of a tangible effect on either war for years. It's not a pet war if you do something effective about it.
(I did help with getting some...erm...stuff into Ukraine in 2023, but that's two years ago. I'll also dare to say that's a hell of a lot more I did for that war than someone mouthing off at a conference has done.)
