The longest hatred is phrase coined by historian Robert S. Wistrich to describe antisemitism.
I would say it is back, but the truth is it never left. From the Black Death to the Great Depression to Islamic radicalism, hatred of the Jewish people excuses and placates bigots of all stripes.
It also seems that it is catching, now the Americans are the new Jews and some people have wondered if the Iraqis might be the next Other, to be shunned and despised.
Recently I noticed that David Duke of the Ku Klux Klan has joined ranks with Cindy Sheehan in his screed Cindy Sheehan is Right. The villain? Well of course it is the Jew and his desire for world domination.
I read some of the ravings of the early Nazis in Wistrich's Hitler and the Holocaust and I could not help but notice the same kind of unreasoning hatred, mindless bigotry and affinity for paranoia which seems to be so much a part of the the antiwar movement. The Nazis were able to do the things they did because they believed they were saving the world, they too were convinced of the essential rightness of their insane Final Solution.
Today much of that same hatred can be seen in the left, both here and in Europe. People will deny this, but answer this..if the young people rioting in France had been Jewish, would people have hesitated to name their race or religion or creed? Or would it have been considered proof of their nefarious intent to take over Europe?
UPDATE: According to an editorial by Ralph Peters in the New York Post sunni insurgents have made a point of expressing their "love" for Cindy Sheehan and her kind. Imagine that, her son's murderers love her. I bet Casey would be so proud.
