Why is there only 1 piece of bread? Who sabotaged all the bread?
From an Arab point of view, European Jews who came to a country they controlled and turned it into a Jewish country. Some of the process was done fairly and legally, but some of it wasn't.
From a Jewish point of view, you blame the Romans who evicted us in the first place and the Arabs who didn't accept us when we decided to come back.
A classic example is illegal Jewish immigration during the British mandate. From an Arab point of a view, it was a crime like the current Border Crises. From a Jewish point of view, the British rule was illegitimate since a higher power deemed the land ours. It's hard to justify the Jewish position without theological belief, which is very problematic when many Jewish theological authorities dispute it.
In the end, there is only 1 temple mount, but both sides care about it more than their own life...
To me, Jewish welfare is more important than justice and fairness. But I understand outsiders who disagree.
