It’s not a genocide because of collateral damage. It’s a genocide because they used wholly inappropriate 2000 lbs bombs on civilian targets, used starvation as a tactic, refused to let meaningful amounts of humanitarian aid in, bombed schools and hospitals, and used genocidal language that demonstrates intent.
Go ahead and defend Itamar Ben-Gvir if you want but he’s a Kahanist. Go ahead and defend Netanyahu but he’s the one who is a disgrace to Judaism and arguably the worst leader of a major power in my lifetime. War crimes have happened. Mass graves exist and torture prisons exist. Genocide requires intent and I’d argue there’s been dozens of statements by members of Israel’s cabinet that constitute a very strong case.
