I more or less agree with you (if it were a _genocide_, you'd expect Israel to be equally targeting Palestinians in the West Bank and in Israel proper), but the report does have some specific examples of things that seem to go beyond "just" urban warfare. For example, Israel denied shipments of baby milk powder, which can serve no legitimate military purpose (except trying to prosecute the war via starvation of babies, which is illegal). When combined with the public statements from Israeli government officials that denigrate the Palestinians in Gaza as animals, I think there's definitely _some_ crimes against humanity being committed by Israel.
