>About 2.5% of the inhabitants of Gaza have been killed in the ongoing war, constituting fewer than 0.5% of Palestinians worldwide.
My understanding is that the agencies in Gaza have not only lost their ability to tally the dead, but have not been tracking deaths where a corpse has not been located.
Not to mention that this is the tail end of a long process that began with the Nakba. The fact that theres a remnant refugee population that has been removed from their land and isolated to a small stateless fragment, is already in meeting with definitions of genocide. Bombing that remnant into the dust is underlining the issue.
Sure, it's been going on for a long time. Close to a million Palestinians were expelled (or fled) from Israel after its founding, and close to a million Jews were expelled (or fled) from various Muslim-majority countries around that time.
The former is known as the Nakba (as you highlight) and well known. The latter, not so much.
