Taking hostages has practical benefits. Indiscriminate killing of folks that don't present a threat isn't practical.

Every single one of those combatants that left the fence that day had a limited amount of ammunition on them. Practically speaking, most US soldiers will patrol with about 7 magazines with 30 rounds in each magazine, plus two pistol magazines. Add another magazine in each firearm. A typical double stack magazine will be about 17 rounds, so we're talking about less than 300 rounds for a full load-out.

In the case of Hamas, they are using imprecise arms like AK-47s. They likely have no optics like red dots or scopes and are just using iron sights. Match grade AK-47s probably have 2 to 4 MOA of accuracy under ideal conditions with modern optics and meticulously handloaded ammunition using modern bullets.

Between poor accuracy and the need to occasionally lay down suppressive fire, 300 rounds isn't going to get you very far.

Unlike US warfighters, the Hamas warfighters also have no ability to call in close air support or be re-supplied. If you have a limited number of rounds and the only potential for "re-supply" comes from enemy combatants, the one thing you don't do is waste ammo on folks that aren't a threat like women, children, elderly. You prioritize fighting age men and in the case of the IDF, fighting age women as well.

RPGs are especially valuable and limited in supply and would likely be reserved for tanks, attack helicopters and vehicles that present threat. It's highly unlikely a reasonably trained fighting force with limited ammunition and explosives would waste them on non-threats. Not saying it didn't happen with any of those warfighters, but the majority would be more disciplined than that, especially coming from an environment plagued by scarcity. US soldiers pretty much have unlimited access to ammo and support and they aren't wasteful with ammo when there isn't a prospect of prompt resupply.

Honestly, I don't know how someone can see this take as unhinged unless they've been largely brainwashed into accept the narratives spun after October 7th.

When someone or some entity intentionally deceives you (which happened a lot with respect to October 7th. e.g. 40 beheaded babies), the only practical response is to assume maximum deceit so they are forced to present evidence to actually support their testimony about what they say happened.

No critical thinking person should accept the official Israeli government's accounting of what happened on October 7th at this point. “Fool me once, shame on you, fool me twice, shame on me”

Anyways, the truth about what actually happened that day is far more knowable than we currently know. All that is needed is transparency. Release everything.
