This one's not over religion, Frank. At least not from the point of view of the Palestinians. Before the Europeans started settling in what is now Israel and the Palestinian Occupied Territories, Muslims, Jews, and Christian Palestinians (those whose ancestors had been living there for centuries) were living in harmony together on that land.

When the Europeans started settling in the region, their aim was supremacy, and to take every bit of land they could aquire by any means necessary.

So from the perspecive of everyone, with the possible exception of the European Jews, it was never about religion, but only about land.
