I didn't really mean for it to be a conversation stopper. Pauses, are useful though. I'm about exhausted myself. Probably due for a pause.
The fact that the Arab nations have been using the Palestinian's cannot be denied - it does not mean the continued theft of their land, abuses of their rights and liberties should be allowed to be continued....
While it may seem that there is a cynical "using of the Palestinians" going on, in reality it is resistance quite admirable. In defense of Right of Return. If Palestinians went ahead and allowed themselves to become absorbed in other countries, they would be surrendering that right.
If Nakba was unjust, and it is allowed to stand, then we as people have given up on justice. As you say, we are supposed to be progressing as a species.
