The Holocaust is one of the most gruesome attempted genocides of recorded history. Around 2/3rds of Jews were murdered which represented around 30-35 percent of the total global population of Jews.
The deaths of Palestinians in Gaza, the majority of whom supported Hamas I would add, is concerning in the sense the speed of the deaths. At least the moment though it’s no where even close to what happened to Jews.. Less than 2 percent of Gaza’s regional population has been killed, and from global perspective a fraction of a percent of Palestinians.
