A reader of Glenn Reynolds points out that the artist who created the Obama Joker poster is a Palestinian-American. I would note further that he is a Palestinian refugee, as defined by the United Nations.
Under UNRWA’s operational definition, Palestine refugees are persons whose normal place of residence was Palestine between June 1946 and May 1948, who lost both their homes and means of livelihood as a result of the 1948 Arab-Israeli conflict. UNRWA’s services are available to all those living in its area of operations who meet this definition, who are registered with the Agency and who need assistance. The descendants of the original Palestine Refugees are also eligible for registration. When the agency became operational in 1950, it was responding to the needs of about 750,000 Palestine refugees. Today, 4.6 million Palestine refugees are eligible for UNRWA services.
Of course, for me, the real irony is that the guy who critiqued—and slammed—the Joker poster is the guy who created the poster of Bush as a vampire.
