:::Whether I'm an Israeli Jew or Palestinian is irrelevant, to my mind.  Suffice it to say that I'm perfectly willing to make or hear jokes about my ethnic group(s).  I am partially Scottish, and presently have a joke on the Ref Desk about me being thrifty, since this is a supposed characteristic of the Scots.  I could refrain from making such jokes and accuse anyone who does of being a racist who propagates ethnic stereotypes, or could only do that if those who make the jokes aren't partially Scottish themselves.  But how would that help to increase understanding between groups ?  The world would still think we Scots were cheap, and then would think we were humorless, too.
