The dynamics is that one side cares about history and the truth and the other side is a whitewashing campaign for genocide.
"Hamas surely deserves some credit for the deaths" This is literally equivalent to saying the Jews deserved [some credit for causing] the holocaust.
There are people in this thread breaking down the history from literally 139 BC to the current day (although hardly anything before 1920 is actually relevant to the current conflict).
To handwave all the complexity away when it's presented to you in a form that would take only a few hours to fully digest and say "both sides"... it's definitely a choice.
Is Hamas technically at fault for giving Israel an excuse for committing genocide?
I guess, if you think such a thing is even possible.
