YMU:Arabs descend from Ishamel? I could have sworn they descdned from one patrilenial tribe situated in the Hejaz and emerged as aPeople some 400 years before th Common Era (BC). No offence if you get your history from the Bible but i tend to lean towards actual history and science, funny that way I guess.
Jews, anywhere are NOT indistinguishable from Arabs because of a little thing called a Genetic Marker. Using Markers, and specifically Y Chromosomal Modality, we know for a fact that todays Jews, Mizrachi, Sefardi, Danni,Yemeni, Bukhari, and even Ashkenazi all directly descend from the same Jews that were nearly crushed under thr Roman heel.
There is a tiny minority within the Arab People whoa ctually are nothing but converted Jews, as we see intrestingly anough from the Ashkenazi angle given your false belief, from a single case of congenital deafness shared between two clans: One Ashkenazi, the other "Palestinian" showing without a doubt a direct lineage.
Arabs are in fact a dinstinct People. "Palestinians" though only gained the distinction after 1948. They did not exist prior to 58 although there can be sen stirrings as far back as 1834 and the 1834 Riots, aka Nablus Riots. Still, even then they violently opposed any identity other than that of "Southern Syrian." In 48, as satted,, they coopted the term "Palestinian."
Ethiopian Jews are in fact less directly descended having sprung from a single garrison of Jewish mercenaries from the Tribe of Dan, oringally deployed to Elephantine in the Nile. There thye intermarried with locals and adopted certain local habits albeit with retention of non-Rabbinical Judaisim.
Zionism is a secular creed and rejects Biblical inheritance. Its claim rests with true histroy and science. Easily put: Arabs equal Arabai (Hejaz), Jews equal Judea. Ma'sah;dah was not a Fatah fort, nor was Jesus a member of the PLO.
