Riiight.
Not quite sure what flavor your "Riiight" is. But when I was a teen and pre-teen, if you said "Palestine" you meant Israel. As I understand it, that was general usage from around 1900 on. There were no "Palestinian" Arabs, other than a few Bedouins. Most of the ancestors of today's "Palestinian" migrated, mostly from Trans-Jordan and Egypt, in response to economic opportunities created by the Zionist Jews.
