My belief is that Zionists think they have a right to make a state in Palestine because their god promised it to them millennia ago and because Jews had their kingdom there in Roman times.
I would challenge you to think about this in a different way. Yes, there are some extremely religious Jews who believe in some sort of G-d-given right to the land, but even that is arguable for reasons of complex Jewish theology that I won't bother to get into here. But for most Jewish people, and certainly for most Israelis, the primary reason for wanting a State is not based on religion or even on ancient history (although that certainly plays a role). It is based on the desire for a national self-determination, the same as the Kurdish people, the Catalan people, the Scots, the Tibetans, the Cypriots, the Serbs, the Croats, the French, the Spanish, the Americans. It is no different, except in one way. And that is the need for safety and security. The Jewish people, quite unique in the world, need a place to be safe. It is also based on the right of return to an ancestral homeland.
I would disagree with you that Jews and Palestinians want the same thing.
How so? Palestinians want national self-determination in what they consider their ancient homeland. The Jewish people want national self-determination in what they consider their ancient homeland. The Palestinian people want to return to a land from which they were expelled. The Jewish people want to return to a land from which they were expelled. The Palestinian people want an end to oppression, equality and dignity. The Jewish people want the same.
So how are they different?
I have never demonized Jews ...
"Demonize" is a catch-all word to describe dialogue which is critical of the Jewish people or which denies to the Jewish people things which would normally not be denied to others. Saying "Jews stole land" is not a criticism of Israel and her government -- it is demonizing the Jewish people.
the English promised a home for Jews in some place other than England and since they had the mandate over Palestine they offered it to the Jews, primarily Europeans from central and Eastern Europe who had survived the Final Solution.
Well, in fact, the land was promised to the Jewish people in 1917 -- before there was a Final Solution. So, your claim is patently false. And the British did not offer the land to the Jews. The British offered to assist in facilitating the re-constitution of the Jewish National Home. The difference is the agency of the Jewish people.
The problem was that Muslim Arabs with smaller numbers of other groups such as Christians, Jews, and Druze, were already there and had been so for centuries.
No, the problem is not the presence of Muslim Arabs. There is plenty of room for both. Just look how many millions of people live in Israel and "Palestine" and Gaza today! Compared to the barely half million in 1900. Look how many Arab Muslims live in Israel. The problem is not the presence of either ethnic group.
So, Zionists wanted a Jewish state (not a mere home among Arabs)
The Jewish people wanted a Jewish State, not a mere home among Arabs. The Arab people wanted a Palestinian State, not a mere home among Jews. Seems fair, don't you think?
and Arabs did not want to be displaced and dispossessed
It was never the intent to displace or dispossess the Arab people. (As is evident by the high percentage of Arab people living in Israel). Any displacement or dispossession which occurred is a DIRECT result of Arab aggression against Jews.
So, the point of going into all this with you is to point out that demonizing of the Jewish people moves us backwards rather than forward. It is not valid criticism of Israel to make broad sweeping statements about stolen land and apartheid and occupation and oppression and the lack of rights of the Jewish people.
What discussion should be about are concrete, practical plans to move forward towards a solution to the problem.
