If you want to be depressed, read these answers by Saudis to a TV interviewer's questions "Would you, as a human being, be willing to shake hands with a Jew?" and "If a child asks you 'Who are the Jews?' what would you answer?"
I'm sure the answers would be quite different if Jews were asked "Would you, as a human being, be willing to shake hands with an Arab?" and "If a child asks you 'Who are the Arabs?' what would you answer?"
Thanks to my old and dear friend Jim K. for the link.
