In Arabic Yahudi-Yahud (اليهودي-اليهود) refers to a member of a religious community. The word has neither ethnic nor territorial significance. The same is true of Jew and all languages that use a cognate. Jew does not come from Iudaeus/Ιουδαίος, which means Judean but from Iudaicus/ιουδαικός, which means Judaic in the sense of practicing a religion from Judea. Classical Roman and Greek writers were well-aware that almost no Judaic person was a Judean.

Because post-Nuremberg genocide is an atrocious and heinous international crime, the Zionist movement attempts to distract from genocide directed toward Palestinians by means of false claims about events alleged to have taken place ~1400 years ago.

A Zionist propagandist attempts to create a hegemonic discourse to legitimize and to normalize Zionist genocide of the natives of Palestine by reference
1. to the Holocaust,
2. to a mythic or fairy tale past, or
3. to genetic anthropology
even though no cognizable defense to a charge of genocide can be constructed by means of such references.

The Pentateuch tells us that Levantine Arabs have been part of the population of Palestine since Patriarchal times (e.g. Ishmael). From the 1st century BCE Levantine Arabs (including the Herodian dynasty partially of Nabatean Arab origin) have provided the political military elite of Palestine.

[The Tobiads, who were part of the Judean elite in the early 2nd century BCE also seem to have been at least of partly Levantine Arab origin. A Tobiad may have built a Temple to El-Yahweh at 'Araq el-Emir.]

After the Herodian dynasty collapsed at around 100 CE, the Romans unsuccessfully tried to rule Palestine directly. In the end the Roman government put Palestine under the rule of local Levantine Arab foederati and Levantine Ghassanid Arab dependent sovereigns.

American, European, and Israeli scholars have shown that there was neither Islamic conquest nor Arab colonization. Crossroads to Islam by Nevo and Koren addresses the crystallization of Islam into its final form in Palestine.

After conflict with the Sassanid Persian Empire drained the Roman Byzantine Empire, the latter Empire retrenched and left Palestine under the rule of a tributary Arab state run by the local Levantine Arabs. After the Sassanid Empire collapsed under the weight of the conflict with the Roman Empire, Palestine, Mesopotamia, Persia, and Arabia coalesced into an Arab state.

The Palestinian population did not change from 630 CE to 640 CE.

Islam developed in Palestine out of the Judean Christianity, which was the religion of the Palestinian peasantry, in which Jesus was the Messiah but not divine, and which had become the religion of the Arab foederati. Islam is a native Palestinian religion that has deep roots in the country while Judaism had become a Mesopotamian religion that was practiced by a population non-Judean origin and that had only superficial mythic connection to Palestine.

How did Judaism become a religion of non-Judeans?

Nowadays we have a fairly good understanding of the historical political economics of the early Roman Empire.

Augustus and successors introduced economic reforms that outraged traditional mercantile interests in the Levant. The economic reforms were associated with the Roman Imperial Cult. The El-Yahweh Temple Cult became the rallying religion of the opponents of economic reform and became the focus of the Judaic War, the Qitos War, and Bar Kochba Rebellion.

Rome won, and Biblical Judaism was shattered in Palestine as the Judean peasantry (90% of the population) passed into Christianity while Mishnaic, Talmudic, and Rabbinic Judaism became the religion of a non-Judean-origin mercantile population. Judaism went out from Palestine, but Judeans and other peoples of Greco-Roman Palestine never departed from their homeland en masse.

The real history of the time period is much more interesting than the religious nonsense.

Every element and claim of Zionism is a lie meant to legitimize and to normalize the genocide that Zionism envisioned and that the Zionist movement as well as later the Zionist state have perpetrated.
