The reason the world is upset with Israel is because Israel was killing one child and wounding two others every eight minutes, and killing two mothers every hour in Gaza; it kills or injures 11 children every 24 hours and kills 200 to 300 civilians every 48-96 hours in Lebanon. Israel cause more than 10 children per day lose a limb; at least 21,000 children have been disabled and around 44,000 children have suffered “new war-related injuries,” and 60,000 orphans had one or both parents killed. It's not because of antisemitism.
No amount of propaganda should convince you that the systematic murder of 100,000 people—including ~25,000 children—in 1,000 days is self-defense and not a genocide.
