Where do you recommend starting?

I prefer starting at the Ottoman property laws, which were adopted by the British Mandate, by which the Jewish purchase of land was perfectly legal.

I'd start at episode 1, since it covers this with far more nuance than "it's legal therefore it's okay".

Thank you, I'll read episode 1. Episode 1 of what?

In the meantime, I would really appreciate a summary of why "it's legal therefore it's okay" is not a good answer. The Ottomans deliberately enacted liberal property laws to increase immigration, and thus tax collection, from the area. It was literally the stated goal of the government at the time.

Episode one of the aforementioned podcast?

One answer to this point in particular is that this wholesale liquidation of the land was made by rich landowners living far away, and cannot be treated as the Palestinians selling their own land away. The people actually living on the land had no say in this.

Their land? As far I can remember, Israel is not a native Arab land. It was also not a native land of Ottomans or British. History is most of the time not fair but there are occasions where former colonisers and conquerors have been forced to give up their captured land. Restoration of Jewsih state Istael was one of such occasions.
