(Highlighting mine.)
Regarding the highlighted part, Israel itself disagrees with you about the percentage of military deaths in Hamas' attack:

Your statement is factually incorrect per the statistics from Israel—not from Hamas and not from any anti-Israel source, but from Israel itself. If you work out 318 out of 1,200 as a percentage, you get 26.5%, so the percentage of civilians killed in the attack was 73.5%.
Yes, the attack was atrocious and killed vastly more civilians than military personnel, but the above demonstrates that you've rushed to some unevidenced conclusions and unsupported claims.
The vast majority of the 11,000 Palestinians killed have been civilians. See above. I will reiterate:
not even the IDF has denied this. There's a reason for that.
Yet not a single reputable expert or reliable organization has denied the civilian death toll in Gaza.
As I said, if you know something all of those journalists, organizations, and countries don't know, feel free to contact the IDF and tell them that they should start denying the Gazan civilian death toll too.
