"people seeing mangled corpses of innocent people and feeling it's unjust to bomb civilians." - If protestors against Israel were honest about this reaction, they would protest waaaaaaaay more vehemently against Hamas for deliberately murdering civilians including beheading babies. But anti-Israel protestors are not honest or impartial. They are racist against Jews.

Also, unless you can concretely describe how Israel can use its airforce against Hamas without creating the degree of civilian casualties you’re protesting, then all you’re really doing is advocating that Israel should commit suicide. Israel should be able to use its airforce against Hamas. There is no way for Israel to use its airforce in ways that creates fewer civilian casualties; Israel’s already doing the best to avoid civilian casualties that it can.
