You obviously know little of what happened in 1948, but don't let`s put that aside for you must have some knowledge. For example, not only Palestinians became refugees in that year but also thousands of Jews from East Jerusalem, Gush Etzion, etc. They were not allowed to return to their homes as well. Refugees are refugees, does not mater either they are Arabs or Jews. The tragedy was the SAME for BOTH people (not just for Arabs) and it was initiated by Arabs and not by Jews.
