Also yes, imprisoning a civilian population in a location and then bombing that location is genocide. They are clearly and deliberately exterminating civilians. The fact that we didn't remove all support the instant they started doing that is appalling.
Also before you even start with the whole "hamas is using the cavilians as human shields." Yes, they are. But that doesn't mean Israels solution of "kill them all and let god sort them out" is remotely acceptable.
