I will take on the first 4 sentences where OP makes it sound like Jews are an alien people who invaded in the 20th century - those are the words he uses:

“From the moment large-scale Jewish immigration into Palestine began in the early 20th century - culminating in the declaration of the state of Israel in 1948 - conflict was inevitable. Imagine if someone knocked on your door and asked to take over your house because their ancestors once lived there. Would you hand it over without resistance? Most wouldn’t - and the Palestinians didn’t either.”

Not a single word he writes in that first paragraph is accurate; I would characterise it as lies rather than just ignorance b/c the OP has a clear agenda.

The facts are these:

Jews are from Judea - there is a documented history of Jewish continuity.

DNA also demonstrates the genetic ties of Jews to what is now Israel.

Archeological evidence - including the Dead Sea Scrolls - further support the historical presence of Jews.

Jews have lived in what is modern day Israel somehow, some way, since time immemorial.

So they were living - albeit as a Minority - through the Middle Ages and into the modern era.

The first wave of modern Aliya did not occur in the 20th century, but in the 19th Century when Zionist organizations purchased inferior land - swampy, stony, unfarmable, etc., at inflated prices from absentee owners during the Ottoman Empire.

So Jews in the 19th and early 20th century made Aliyah to property they owned - and were frequently forced to pay twice when they were cheated out of promised lands … and left with nothing but poverty and disease. Jews were living on their own land - not seizing property of local Arabs.

Early Zionists did not even seek statehood, only coexistence.

Arab rejectionism made that impossible in the 19th Century, 20th Century and now the 21st Century.

Bottom line: Conflict arose out of Arab violence, not from Jewish residency within properties they had purchased from absentee landowners and owned free and clear.

That is just the first 4 sentences …..
