They're not really engaging with you, just like Israel isn't really interested in a dialogue about the situation. They just need you to think there's a civil dialogue being had so that we don't realize the need to stop them by force.
This is quite literally how they see the world. Every child in Rafa is this child. Every adult is a terrorist cell leader. Every refugee is going to want revenge. Every survivor is going to join the next revolt.
Its the same logic American colonists used on First Nations people, as they carved their way westward. Its the logic Serbians used as they butchered their way through Bosnia. Its the logic American soldiers used in Hadditha and Kandahar. Children are just tiny future evil adults and killing them is right because they are incapable of doing anything but wrong.
I'm neither pro-Israel nor pro-Hamas, but I believe the correct answer is "same as in every other war".
In other words, the maximum rate of Gazan casualties you will accept depends on the maximum rate of Axis casualties you would have accepted in WW2. That might be zero or it might be fairly high.
What worm ate your brain and made you think that is the choice of sides here?? Fighting for Palestinian emancipation has nothing to do with being pro-Hamas you dingus.
The going rate is 1:30 Israelis to Palestinians in revenge killing. For killing each Hamas militant they're allowed to kill around 20 as collateral damage. 50% in Gaza are children so 10 kids per Hamas militant is okay according to the Israeli government.
As per item 2: If the enemy was using them as hostages I sure as shit wouldn't just bomb the building and kill everyone. I'd prefer to use special forces to go in on foot and secure the building with minimal casualties. And only when diplomacy fails.
The enemy was using them as shields because they didn't think you'd be that fucking stupid to just bomb everyone; they assumed you had some empathy.
