Come on, nearly half of the inhabitants of Gaza are/were under 18. "Surveys" cannot make collective punishment legal, or annexation and ethnic cleansing for that matter. I'd say outright cutting off a whole population from food and going on TV to rant about how even the babies are terrorists isn't self-defense or security. If anything it's with a second set religious extremists that needs Hamas just like Hamas needs them. And in similar fashion, they use "Israel" as a shield for what they want, despite the Israelis who do respect human rights and international law, and get threatened for it.
> You’re trying to separate Hamas from everyday people in Gaza
They are separate. Each person is responsible for their actions. You can't speak of democracy and then casually ignore this.
