Why do people seem to demand "proportionality" in casualties when it comes to Jews?

I'm guessing people trot out the proportionality argument..because they really want more dead Jews not less dead Palestinians. One side (ours) has done everything possible post 10/7 (because it was a massive intelligence failure that allowed Oct 7 to happen) to protect their own people with defensive weaponry. The other side quite literally prays for mass casualties and co-locates every military installation inside civil infrastructure. The sufficient lack of dead Jews for some is certainly not a reflection of a lack of trying on the part of Hamas, Hezbollah, the IRGC, the Houthis, and Shia Militia groups.

Obviously, we all know this - but it's striking how little people who seem to breathlessly follow this conflict, seem to understand that civilian casualties are a goal of Hamas because they (correctly) know how powerful it is for bringing back the blood libel antisemitism. Or, rather, they don't care. Because if they did, they'd be clamoring for Egypt to actually let in aid, and provide an escape valve for non-combatant Gazans.

Crazy that people are marking the 1,000 day of the Gaza War (assuming they aren't just calling a genocide), considering that Israel didn't invade immediately and was heavily criticized for waiting several weeks. Now, I think there's a genuine argument to be made in how Israel prosecuted the war, however, not sure how other armies would have tried to achieve their objectives given that Gazan has more underground tunnels than New York has subway.
