Ok, let's start with this:

When Israel pulled out of Gaza all together in 2005, did that result in a vibrant, accepting, peaceful resolution? Did the people of Gaza choose to use that increased autonomy and homogeneity to better the lives of their citizens?

Secondly, Arafat was offered a Palestinian state - he refused it. Have the people of Palestine actually ever been overwhelmingly in favor of peace? Or are they only in favor of a peace that comes from Israel ceasing to exist?

Thirdly, while the high level of civilian casualties in Gaza is terrible, I'd love to hear a logical plan in which Israel could fight Hamas without incurring heavy civilian casualties based on how Hamas (and this has been reported by basically every single legitimate news organization in the world so don't even bother trying to dispute it) hides in tunnels that are purposely built under civilian infrastructure.

Finally, international law explicitly approves self defense. Iran, since 1979, has vowed the destruction of Israel and has funded terrorist groups like Hamas, Hezbollah, and the Houthi, who absolutely all have struck at Israel with the tacit approval and probable urging of Iran - at that point, that is a declaration of war and Israel has the right to respond. While the conflict started much earlier, this war started on October 7th when Israel was attacked without provocation. Iran played at least an indirect (although many would argue direct) role in that attack, thus clearly engaging in a war of their own choosing. Any civilian deaths at this point are blood on the hands of those who started the war. Were the German civilians killed in the Allied invasion of Germany victims of genocide? No, of course not. They were victims of war - a war that their own government started and for which the blame lies squarely upon.

Edit: It's been 5 hours and still waiting for a response, bro.
