Yes, they are doing a genocide.

I'm not sure what other options are available at this point though.

Hamas is extremist to the point where they would be doing a genocide as well if they were in the position to do so.

People say separate the Hamas from the people, but that's really hard when the members of Hamas are of the people and have the support of a good percentage of them.

If Israel invades on foot and Hamas is threatened they can simply fade back into the population and wait to try again. And the general population will support them in doing so.

The creation of the state of Israel was a mistake and the rise of Hamas is the direct result of decades of apartheid practiced against the Palestinians by the Israeli state.

... But as the issue stands today, I can't blame Israel in taking extreme action to end the conflict that's dragged on for nearly a century now.

There is no reasonable path to peace. A two state solution would end with the states at war anyway as both states have extreamists who want to genocide the other in government positions.

And there is no where that would accept the Gaza population as refugees even if you could get them to leave.

So what's left?
