The Jews have always considered themselves a people, the Quran calls them a people, League of Nations documents call them a people.
Non Jews living in Palestine weren’t called a people until recently,
for political advantage.
The Palestine Symphony Orchestra was a Jewish orchestra.
The Palestine Post was a Jewish newspaper (in English).
Palestinian Arabs who fought Jewish immigrants
called themselves “Arab Liberation Front”.
“Palestinian” is defined by no more than his interactions
with those Jewish immigrants.
You ignore it all because it hurts your narrative.
