I like how quick you are to shift the goalposts from “there’s no evidence. None at all” to “oh that evidence you provided? It isn’t conclusive evidence”. Keep cheering for genocide if that’s what you want to do, there’s no need to pretend this is about anything else.
This is not a court proceeding, so saying “hearsay is not evidence” is pointless. Witness testimony before a court would be evidence. And all we know as of now points towards Israel doing it. The details will have to be proven in court, when they eventually get their Nuremberg.
