Urban conflict in general produces civilian casualties with women, men, and children dying in proportions matching the demographics.
In the Russia-vs-Ukraine war there are relatively few dead children because the demographics of both counties skews towards adults — not because of the military doctrine of either side. Children make up less than 20% of the population and hence less than 20% of the civilian deaths.
Gaza has ridiculously skewed demographics with fully half of the population below the age of 18. (Don’t take my word for it, just Google it.)
Hence the civilian deaths in Gaza reflect this skewed demographics. Fifty percent of civilian deaths are children not because Israel is targeting children (as if they were cartoon villains!) but because fifty percent of the civilians are children!
I don’t disagree with the facts. It’s just that facts are being presented without the background detail to make Israel look insanely evil. Which they are not… they just a normal amount of evil.
