Nobody’s calling Hamas the good guys. We’re pushing back on the narrative that the hospital itself is somehow involved and thus exempt from the normal protections in war.
Hospitals will treat anyone that comes in by default, and in the case of a Gazan hospital, what choice would they even have anyway? You can’t call the authorities if Hamas are the (de facto) authorities. You treat the hostage and get them to GTFO as fast as possible before you get bombed.
You are falling for the IDF narrative that says all Palestinians are Hamas, as if they have any kind of choice in the matter.
