Transfer - again

Glenn Reynolds links to this post by Joel Rosenberg, where Joel raised a possibility of transfer as a possible solution to the Palestinian problem. Glenn calls the plan "ugly", and he of course is not the only one. As an update, he also links to an old post of mine on the subject. I wonder if he still thinks it is ugly, and why. Come to think of it, none of the people who call it "ugly" have been able to rationally explain their point of view. If anyone, Glenn should be able to do it.
