From the article: « Proponents say the law helps ensure Israel's security and maintains its "Jewish character". » Which is eerily similar to the arguments in favor of the 1935 "Law for the Protection of German Blood and German Honour" (Nurenberg laws) in Germany, which forbade marriage between Germans and Jews.
The demographic difference between the two is staggering. If all Palestinians received right of return to Israel, Jews would immediately become a political minority. The Germans had no equivalent statistical reasoning other than racism. Think about the context before you compare people to Nazis
Ok? If Russia wins their disgusting war in Ukraine, and then tries to prevent Ukrainian refugees from returning to the homes that they left, would you say that Russia is in the right, since otherwise Russians would become a minority in Ukraine?
The right is called "right of return" because these people lived there before Israel waged war on them and threw them out. Most (but certainly not all) of those waging the war were recent immigrants to Palestine, and they performed an ethnic cleansing to create their own space - extremely similar to the "living space" concept of Germany, though more necessary.
The parallels are in fact striking, not absurd.
