I've read quite a lot about this and am familiar with Operation Hiram and the tragic massacres you've mentioned.

There have been many, many wars in the 20th century, and nearly all of them have included massacres. But '48 is rarely compared with anything other than the Holocaust, to which it bears very little resemblance.

The Holocaust was the physical destruction of some 2/3 of European Jews amid circumstances of mass shooting & gassing, forced starvation, and slave labor on a gigantic scale.

The Nakba saw massacres, expulsions, and flight during an existential war which killed perhaps 1-2% of the populations of each side.

The massacre that killed my great-aunt and great-grandfather in Poland had a death toll of around 2,300. No one has heard of it, and there were hundreds upon hundreds of massacres like it.

The Babi Yar Massacre alone killed more Jews in 2 days than the total Arab death toll in the '47-'49 war, including soldiers from neighboring states.

Comparing the Holocaust to the Nakba is as absurd as comparing the Nakba to the Las Vegas shooting, in numerical terms. I can think of two reasons you'd do this: hatred or ignorance.

If the reason is hatred, there's nothing for me to say.

If it's ignorance, then I'd encourage you to look at simple things like the relative death tolls (between sides and between events), the number of Palestinians vs. European Jews who remained in their homes with their families, and the numerous conflicts that are much more similar to the '48 war than the Holocaust.
