If I thought you meant literally "sticks and stones," I'd conclude you're willfully ignorant and disengage.
Assuming you mean it in the figurative sense, as in that Hamas has qualitatively vastly inferior weaponry than the IDF, I agree.
That's why they're using asymmetric warfare, including such was crimes as fighting from inside "protected" zones and facilities, attacking unarmed civilians, etc.
Insurgencies, especially by people who delight in dying if it means inflicting casualties on their enemy, are notoriously difficult to defeat. Winning requires gaining the support of (at least a sizable minority of) the populace, which would be incredibly difficult in Gaza.
