Clearly the absolute number of casualties (not even civilian casualties in this case, that is allegedly more like 15k) is not sufficient on its own to define a genocide.
- They’re displaced because there was active fighting in their homes.
- Hospitals were destroyed because they were being used as military outposts.
Neither of those violates the rules of war, though Hamas using hospitals as outposts is a war crime.
I think it’s a tragedy the government of Gaza brought this disaster down upon them by committing war crimes against their stronger neighbor and then further war crimes using their own population as human shields.
But that’s not a genocide.
Gaza can surrender any time and the collateral damage isn’t out of line with modern urban conflicts. Eg, US in Iraq.
What the second video is supposed to show is anyone's guess.
