According to the CIA world factbook (the only source I could find) the population spread in gaza is:

0-14 years: 38.8% (male 427,450/female 404,288) 15-64 years: 58.3% (male 627,235/female 620,903) 65 years and over: 2.9% (2024 est.) (male 31,655/female 30,112)

Meaning about 30% of the population are males over 14.

So I guess Israel isn’t disproportionately murdering women and children, theyre just killing everyone. So genocide.
