That's a pretty normal thing to say when the IDF has bombed Gaza into rubble (not ot mention bombing hospirals,homes, schools, shelters, universities, and mosques, and in some cases, using those places as bases before bombing them).
I bet you have the same reaction when people say "Death to the Russian Army" when Russia bombed Ukraine, getting inspiration from the most moral army in the world.
