QUERY: What do you propose happens to the Irsraeli families who bought this formerly refugee land? Your automatic reaction might be "kick them off so that the Palestinian refugees can come back." But then you aren't thinking of the ramicifactions this has for individual Jewish people, which aren't fair.
Firstly, if the law somehow prohibits palestinians from purchasing the land, then it's a bad law. However, if I'm not mistaken, Jewish people have to pay for that property. And many if not most Jewish people probably have no idea about these weird laws. Kicking them off without due compensation would be immoral. They have lives and children too. Telling them to hit the road makes you no better than anyone else, and it is not the fault of recently born Israelis that they were born on the benefitting side. If you want someone to blame, blame the Israeli government instead of blaming (and wanting to punish) the Israeli people who just want to live their lives.
People need to stop looking this in terms of ethnic affiliation. You have to see with better eyes than that, at the individuals who your proposals are hurting.
Not really.
