Nobody serious disputes that Gazan civilians are suffering enormously. The argument isn't about that. It's about whether Hamas represents them, and the answer is: less and less, given that Hamas hasn't held an election since 2006, has siphoned aid money into tunnels and rockets for two decades [1], and on October 7th sent men with garden tools to decapitate Thai agricultural workers [2] and film themselves doing it.
You can condemn Israel's conduct (and there's plenty to condemn) without pretending the people who started this particular escalation were freedom fighters having a bad day.
