And would Israeli polling about Palestinians justify their deaths, too?

Nobody is justifying Palestinian deaths, whatever that means. You don't know my position on the war, since I haven't articulated it here.

I'm simply refuting your earlier claim that only Hamas and Hezbollah is dedicated to the destruction of Israel, while regular Palestinians are fine with it. Hopefully you have the intellectual honesty to acknowledge your earlier claim was wrong, and there was and is indeed broad support for destroying Israel and its civilian population among Palestinian civilians. And not just intellectual support, but concrete actions. Are you familiar with the "pay for slay" program?
