“Palestinian nationalism”
Nationality always has an element of artificiality, but
“let’s pretend we’re an ethnic group for propaganda purposes”
seems to be unique.
Jews have their own culture, history, literature, language, religion etc…
for over 2000 years. Being the descendants of 12 tribes of Israel ceased being meaningful over 2500 years ago.
Comparing Jews to Palestinians, there’s no doubt that Jewish claims
to people-hood are more serious than those of the Palestinians.
