Whether a Papal decree or today s Arab Press, a conduit of official hate was needed to arouse the masses. Perhaps you are thinking about the individual reporters, TV commentators, columnists, who subtly or directly incite against the Jews. What quirk in their personalities causes them to sometimes report the news in an unbiased, non personal way and, at other times when they report on the Jewish State, become virulently personal. Such individuals as Walter Rogers and Gerald Kessel of CNN are good visual examples as TV reporters. When Israel is the subject, their facial expressions show negative emotions like disdain, disgust, etc.
Words take on a bitter, hostile tone and meaning.
Conversely, when they speak of the Palestinians or Arabs, their entire demeanor changes. They are sympathetic and understanding. The Arabs can do no wrong and the Jews can do not right, something like the U.N. syndrome. I am sure they would be astonished if they were accused of adopting the Goebbels technique of preparing the minds of their listeners to attack or, at least, approve of attacks against the Jews with vigor. The media of today has become a player.
