50k civilians dead out of a population of 2.2M. The population of Gaza has increased since the war began. That’s not a genocide insofar as the word means anything.
If it was a genocide you would expect basically 90% of the population of Gaza to be dead. Israel controls the water supply and the food into Gaza, they could just poison the food and water, dropping bombs isn’t even necessary.
I don’t know how to make it more simple than that.
