Well. This is pretty significant. I would say it's rather damning evidence that considerably raises the bar to doubt these claims.
There's a lot I could say here. Hamas is a bunch reprehensible fucks. It's disappointing that we needed concrete evidence because of how untrustworthy the IDF is. But I think the most salient and important point here is that there is no "good guy" or "right side" among the war combatants. It's awful people fighting awful people. Hamas and the IDF both deserve nothing but contempt and scorn, and both should be dismantled for their crimes against humanity.
I've tried to be very precise with my wording because none of what I just said applies to the Palestinian nor Israeli people. The civilians and innocent people are caught between two legions of hell and are the ones paying the price. The kidnapped and tortured Israelis, the Palestinian people -- both of them are suffering at the hands of both Hamas and the Israeli government.
Neither of them care about the civilians. They use them as lambs for sacrifice and control the flow of information to manufacture hate and support for the war. It's become readily apparent that the IDF and Hamas just want to keep fighting, and they're manipulating the civilians to support them. If both peoples were getting the true, unfiltered information -- sights of dying Palestinian children, demolished buildings, accounts of Israeli hostages -- I think they'd be appalled at what "their side" is doing.
I really hope the majority would be appalled, because there can't be any peace until they recognize their shared suffering and humanity. And to be clear, the majority of suffering is clearly inflicted on the Palestinians.
Edit: I'm not angry at the downvotes but damn am I disappointed. You'd think "fuck the people genociding others and fuck the people taking hostages" would be an uncontroversial position, but here we are.
