I am frontpaging this mainly because I applaud Ziontruth's uncompromising defense of the Jewish people. I hope that he doesn't mind, but anyone who posts here must expect for their words to find themselves on the front page now and again.
He's also correct about Arab and Muslim imperialism, a taboo subject among progressives.
"All peoples are an invention, which is to say that all peoples are a social construction who come to know themselves in time and with a starting point, however vague in our understanding."
Peoples are normally formed through a process of evolution, one so gradual it might take centuries to be perceived. Ethnogenesis happens when a group branches away from its parent bloodline and becomes sufficiently differentiated from it—whether in culture, language or genetics is immaterial—to be considered no longer part of the former whole.
In modern times, it seems a lot of "peoples" have deviated from that norm and instead have been created by human fiat, usually in response to some external force. Africa had had many real peoples before the European conquest, but the various "nations" of Africa today have nothing to them but the borders drawn by none other than the Western powers. In the Middle East the situation is the same, and the faux-Palestinian "nation" is like the Lebanese "nation" in its members having nothing common except opposition to an enemy.
The real nations in the Middle East are as follows (most probably a partial list, but still a wide coverage): Arabs, Circasians, Copts, Druze, Kurds, Jews, Persians, Samaritans and Turks. Those are the nations in the ME formed in ethnogenesis as it has always been in human history, while all the rest are anti-colonial or post-colonial creations. It is quite ironic that the Progressives, of all people, effectively advocate the perpetuation of the damages of Western colonialism with their insistence that the contrived nations are real.
"The Palestinians as a people emerged out of the greater Arab nation in its conflict with the Jews toward the conclusion of the twentieth century."
They didn't emerge. That's exactly the problem: People are calling for their treatment as a real nation, but they fail to see this "nation" does not pass the requirements of such. No "Palestinian Arab" has branched out of the greater Arabian nation any more than there is a "Baltimorian American" nation. Beyond trivialities, nothing in the way of cultural, linguistic or racial differentiation has yet occurred with the Arabs residing in Palestine.
"The American people emerged as a people in our conflict with the English during the 17th century."
The American nation took a long time after 1776 until it really formed national consciousness. In the 18th century there was the proto-concept of a "shining city on a hill," but the whole 19th century had to be spent, with the expansion westward and the Civil War, until there could be something like a stable American national identity. Some historians say (though I don't agree with them) it was only after World War One that American nationalism came to be a serious force.
"In contrast, the Palestinians emerged as a people in their struggle to abort Jewish nationalism."
It would be more accurate to say that's been the goal of Islamic and Arab imperialism from the 1890s onward, when Jews from abroad arrived with no intention to live as dhimmi subjects, but rather as free people. As an imperialist goal does not sit well with world opinion, there needed to be some way of inverting the roles of David and Goliath in this conflict. That's where all the talk about a non-Jewish "Palestinian nation living on the land from time immemorial" ultimately comes. It's a PR stratagem, nothing more, nothing less.
