>>5004915dude Arabs are an ethnic group on their own that originated from where you're living in right now and expanded through conquest to form the Arabic Empire and the Sultanates and the Caliphates all over Asia, Africa and Europe.
The thing is that Palestinians themselves are not Arabs, despite what they like to claim, but they're a mixture of ethnic groups that dominated that land: Hebrews, Romans, Greek, Persian, Arab, etc.
I wouldn't say that Palestinians are French tho, since the French Domination lasted for only few decades.
