> Hamas or Hezb target civilians more than the IDF
Never claimed as much. The point is Hamas and Hezbollah explicitly target civilians. (The October 7th raid had a modest CCR of 2:1 inasmuch as there were 766 civilian and 273 security casualties [1]. Break down some of the raiding parties, however, and the CCR is much higher. Comparable to some of Israel's worst raids, or Russia's war in Chechnya.)
> IDF has killed orders of magnitude more civilians than either
This is how multiplying a big scalar by a smaller ratio works.
> We are rounding civilian casualties to integers. This is a necessarily inexact science.
I think what he's suggesting is that of the Israeli casualties on October 7th, we have no accurate breakdown for how many were caused by IDF implementing the "Hannibal procedure". It's possible the answer is "A LOT".
One case in which it is known that civilians were hit, a case that received wide coverage, took place in the house of Pessi Cohen at Kibbutz Be'eri. 14 hostages were held in the house as the IDF attacked it, with 13 of them killed.
