Yes only 36 children out of 1139 deaths does indicate that it was not indiscriminate murder.
This is preposterous. You cannot refute a positive assertion with an incomplete set of negations. Assuming you meant that 36 children out of 1139 deaths does not indicate that it was indiscriminate murder, you would be correct, but the deaths of 695 Israeli civilians certainly indicates that it was, at best, indiscriminate murder of adults.
you can in no way justify israel bombing any target in Gaza which they suspect as a Hamas member if that person is not actively armed.
I made no attempt to justify the IDF bombing Gaza because I don’t think it is justified. The intention of my previous comment is clearly to point out the contradiction between this and your previous statements. Are you a tankie who says most of the Israeli adults killed were IDF conscripts directly affiliated with the army, or not?
If a Hamas soldier went through a Hamas training camp but did not participate in the october 7 attacks, is the IDF justified in killing this person when he is not holding a weapon?
When he is not holding a weapon? In most cases I would say no.
