No, it doesn’t contradict anything about the genocide.
Israel didn’t need to completely destroy infrastructure and also deny foreign aid because of how Hamas fights. How Hamas fights doesn’t justify the IDF killing reporters, or the unarmed children being gunned in the streets, or strapping injured Palestinians to hoods, or atracking aid workers that the IDF knew were coming through, or the most likely true reports of torture. We know all of this is intentional by how Israel acts, and they are using the excuse that civilian casualties are happening despite the IDF being careful, but they keep killing dozens of civilians and getting caught lying about things which is why they are not trustworthy.
Plus Israeli senior leadership has made and keeps making statements consistent with genocide that align with their actions. All of that would still be genocide even if Hamas fought some other ‘acceptsble’ way.
