There's no sleight of hand, just a horrifying reality. It's not just Hamas and Hezbollah. Civilians from Gaza participated in October 7 and poll after poll shows broad palestinian support for the destruction of Israel.
Support for Hamas itself is waning in Gaza due to their brutality, but Hamas began the war with broad support for their genocidal aims.
And would Israeli polling about Palestinians justify their deaths, too?
That is kind of a dishonnest take. You make sure to avoid mentionning that hamas is not only a terrorist organization. It is also an administrative body which has been bringing employment and services to a significant portion of the palestinian population while they have been constantly under strict embargoes, restriction and aggressions for decades.
You can't really criticize people to support the only org that pretend to care about them while the whole world seem to be against their own existence. Most palestinians would just want to live a peaceful normal life but have been expropriated and forced to live in a ghetto. How convenient to feign surprise and indignation that same people would have resentment against those that have been making their life difficult and at risk. Israel created Hamas.
You can draw a parallel to say, part of the colombian population that was supporting Pablo Escobar when the Medellin cartel was providing services that the government was failing to provide to the poorest classes.
