Same is true of the Jews. That argument really doesn’t move the legitimacy of Palestinian claims forward one iota.

Except it is not true of the Jews, many Ashkenazi Jews contain little to no DNA in common with the past inhabitants of the region. If you have any legitimate proof otherwise I would be happy to inspect it.

For 1200 years under the Ottomans, the Ottomans owned everything, and the local inhabitants were simply allowed to reside on the land

Not true again, read about the Ottoman Land Code of 1858 for instance.

It is better to look at the issue of land ownership from the Mandate era forward

Convenient time period for you to chose while ignoring history, quelle surprise.

There is no evidence of a Palestinian state- ever

Wrong again, there is just as much evidence of a Palestinian state as there is a Jewish one. You haven’t even taken the basic step of doing a Google search to check the verasity of your bold statement. First historic reference is from 12th century BCE from Inscriptions at the Medinet Habu temple written during the reign of Ramesses III, 8th century BCE Assyrian texts, 5th century BCE Greek Texts, the Romans then renamed the region Syria Palestina in the 2nd century.

Palestinians were only ever residents on the land, pawns of larger empires for 2000+

As we’re the Jews before this, they were never a mighty empire in the same vein as the other cultures you listed. If that is your rationale you might as well give up now. The Palestinian people have also been present in the region for far longer than 2000 years, the people today still retain the DNA of the Canaanites. My argument is also not that “Palestinians were there first” rather they have been present continuously for several millennia. History, archaeology and most definitively DNA are on my side.

It took 2000 years, since the Roman era, but again, do you say that anyone who is forcibly removed from the land of their fathers somehow loses any claim to that land?

When you are speaking in time frames of millennia yes you have lost the claim to that land as there is no reasonable way of proving your ownership in a court of law. Your argument makes about as much sense as me wanting to claim a piece of Ethiopia due to my ancestors living there before Homo Sapians left Africa. The Palestinians case displacement 78 years ago is still in living memory with documentation and census data to back the claims.

Be careful how you answer that, because Truth is a double edged sword that cuts both ways.

I actually laughed out loud when I read this, your lack of awareness of your own hypocrisy is hilarious!

and at the same time, sold out their own people for the sake of money.

The people did not realise the Zionist Jewish colonisers were planning a heist of their country. Weird way of you to frame it with hindsight.

Land stealing came later, and didn’t last long.

What!? The land stealing is still going on to this day, it never stopped. There are plenty of maps available online that show the year by year stealing of land by Israel in the West Bank by “settlers”.

Arab politics in the 20th century, post 1948 has been highly fractious itself… It’s almost as if they dislike eachother as much as they dislike the idea of Israel existing

You display a distinct lack of knowledge of the history of the region pre 1948, the division of the region or who divided it. Your statement is as idiotic as "European politics was highly fractious in the first half of the 20th century, why do they fight, don’t they know they are all white Christians? You assume discord amongst the Arab and wider Muslim world is a constant, dangerous assumption about anything in an ever changing world. You also fail to understand or comprehend the outside influence that has destabilised the region since the discovery of oil in the region.

The Palestinians are no longer global pariahs, Israel now owns that role, keep up.

I wouldn’t be so sure of that and I certainly wouldn’t bet money on that in the next 25 years.

Well Israel are doing there very best to speed run the collapse of this relationship. No amount of AIPAC dirty money can wash away the stain of genocide, candidates are now running a mile from this dirty money. The Michigan election was an interesting example of this, the AIPAC candidate outspent Abdul el-Sayed, a pro Palestine candidate, by $50 million, outspent by 10-1 and still lost to a Muslim man. The current New York governor is a pro Palestine Muslim man who won the cities Jewish vote. This is the city of 9/11! The tide is most certainly turning, people are starting to question their blind Islamiphobia and wonder who is fanning the flames. The newer American generation is firmly pro Palestinian and anti genocide.

especially if they are allowed to taste some prosperity for a time

You sound just as deluded as Jared Kushner and Donald trump, this is also their thinking. You keep great intellectual company there buddy! Imagine thinking some money will wash away the memory of their mother’s and siblings being indiscriminately blown apart in front of them! Most of the world thinks differently to you, you really don’t get it do you? It is not propaganda but their own lived experiences of occupation and oppression that drives the Palestinians. There is no sweeping a genocide under the rug in this day and age.

It was a nice try there buddy but your arguments are as weak and mendacious as those of the state of Israel’s. We all see you now.
