You’re confusing a political justification for war against a terrorist organization with a racial justification for genocide. There are millions of arabs living in Israel, and they aren’t being killed. Not everything is systemic racism.
And as far as your history goes you’re missing a bunch of wars the surrounding Arab countries declared on Israel. This isn’t a simple “white people bad” situation.
Egypt, Qatar, America, and Israel have been asking Hamas for a simple list of hostage names for weeks with no answer. What’s with that? It doesn’t hurt them to provide a list of names. Is it possible Hamas doesn’t even know how many are alive?
