Israel is causing the suffering in Gaza. Did you fall on your head?
When the killing in Gaza stops, then we can all debate whether Israel killed enough of a "part" of the people in Gaza, or whether the clearly genocidal rhetoric they've used is proof of "intent" to commit genocide and all the other distractions that waste time and energy.
But right now, while the killing is still happening, I think the entirety of every decent person's focus should be on stopping the killing. Biden already almost found the courage to stem the flow of weapons into Israel, for example. That (and more) can be done without using the word genocide.
