I will always have great respect for the Israeli government, which has a religious purpose, but I'd oppose such a decision in all legal ways, just as the honorable people who were ethnically cleansed out of Gush Katif in exchange for thousands of rockets opposed their treatment by the government.
At least the residents of Gush Katif were treated better than those of Deir Yassin. It's not surprising that many Arabs fled rather than risking extermination at the hands of Irgun and its sympathizers. Really, Zionists have no room to bring up the ethnic cleansing card.
By the way, it was interesting to see you in that same post both complain that Palestinian identity was invented during the last century and complain that Syrians had moved there post-1910, when if it weren't for the last hurrah of European colonialism, Sykes-Picot, both Palestinians and Jordanians would likely see themselves as Syrians today.
