"So that is admittedly awful, but that means 75 out of 764 civilians or 3% of the total, versus, say, 70% of 20,000" - (1) Nobody has asserted 70%. Propaganda articles have asserted "almost 70%", which is unclear and different, inflating the digits presented in order to serve propaganda purposes. (2) The 75 number from the Times of Israel article, which you fail to link to, but I will here (https://www.timesofisrael.com/14-kids-under-10-25-people-over-80-up-to-date-breakdown-of-oct-7-victims-we-know-about/) is the number over aged 80 years. How is this relevant and connected with the "almost 70%" of Palestinians killed are civilians? I think you're mixing up numbers.
