Norman Finkelstein's claim that Palestinians'  right of return is "complicated http://axisoflogic.com/artman/publish/Article_62548.shtml

Is it true, as Norman Finkelstein claims, that the right of return for Palestinians is a ‘complicated problem’ – so complex that it justifies him (and the Zionists) saying, “Now, I am not arguing now for a right of return”? [This is what Finkelstein does indeed say on his website] No, it is not true. I have debunked this ‘it’s complicated’ (or ‘not practical’) notion in two articles: here (pdf) and here.

The only thing that makes people say that right of return for the Palestinian refugees is ‘complicated’ is the fact that if lots of the refugees returned then there might not be a majority of Jews inside the green line and this would essentially make it impossible for the Zionists to continue referring to the territory inside the green line as a Jewish state, unless they were to openly admit that their Jewish state is a state of only a minority of the population and risk disapproval of everybody in the world who supports the idea of democracy. In other words, what makes right of return ‘complicated’ is that it is incompatible with the existence of a Jewish state in Palestine—a state that is officially a state of the Jewish people and not a state of all its inhabitants (or even of all its citizens) equally.
