Hamas have encouraged you to think in those terms by reporting all deaths as civilian, whether they are Hamas or not... as well as flooding social media with distressing images of dead and dying children, unlike Israel who are more respectful of the families concerned.
I'd be interested to know how you would fight a terrorist opponent that is deeply embedded in civilian life to the extent that they ensure its activists cannot be identified (unlike normal wars where combatants are uniformed). Can you not see the problem here? And do you really think that Hamas is interested in a peace deal? They have their eyes on the prize, which is to eradicate Israel once and for all ("from the river to the sea").
Have you considered that if Israel wanted the "mass slaughter of civilians" it could easily have eradicated the entire population of Gaza long ago, instead of ~2.5%? The Hamas-controlled Gaza Health Ministry does not differentiate between civilians and armed militants in its reporting. It simply labels all deaths as resulting from "Israeli aggression". Even if you accept without question the number of deaths they report as entirely civilian, the ratio of deaths per air strike is lower than would be expected, despite the fact that Hamas deliberately hide behind hospitals and schools.
Obviously 2.5% of such a massive population is significant and distressing, but it simply does not add up to the claims you are making. Please be cautious about swallowing Hamas propaganda hook, line and sinker and then voicing it as thought it's incontestable.
