It’s worse than that. They weren’t displaced, they displaced themselves. The Arab world said to the people there that they were going to invade and kill all the Jewish settlers, and that after the quick war was over, they could move back and have their old apartment back, or move into the newly vacated one of the dead Jews, suit yourself.
And then the 1948 war did not go as planned.
Well, the current SJW narrative (apart from trendy Holocaust-Denial), is that there are no actual, bona-fide ethnic Jews left in the world. Apparently they all converted to Islam during the Ottoman Caliphate, and the modern, so-called “Jews” are actually “AskeNAZI Khazars,” and, as such, are central-Asian and European invaders that have no right to a land that was never theirs.
Blah blah blah, you get the picture. However, this IS the standard narrative amongst the so-called ‘progressives’.
