The enduring objection to October 7th is that Hamas killed civilians in addition to military targets. But Israel has demonstrated time and time again that they are not at all worried about targeting civilians, even when a "military" target is nowhere in the vicinity of the attack.
Which essentially nullifies the objections to October 7th entirely. Either civilians are off limits or they're not. And Israel has declared war on all Arabs, irrespective of their political affiliation.
