Antisemitism used to mean “someone who doesn’t like Jews,” but nowadays it means “someone that Jews don’t like for some reason or another.” The deliberate trick here is to make you think there is something wrong not with the Jewish baby killers, liars, or scum who are doing bad things but with the person noticing and reacting to the bad things these miscreants are doing.
So, what are the bad things that most people notice about Jews? Before naming and defining the most important ones, let’s first find out what Jews themselves say about antisemitism. Is it a rational and logical reaction to Jewish behaviour? Or is it, as most Jews claim, an irrational hatred of a totally harmless people who have been the innocent victims of human jealousy, vindictiveness, and persecution since the beginning of time?
Theodore Herzl, the Jewish father of Zionism, believed that hostility towards Jews was a natural consequence of their behaviour:
This perfectly understandable reaction follows from the defects of the Jews… The Jews are a people distinct and separate from others, whose interests are different, and often in conflict with those of the peoples among whom they live.[1]
A fact shared by Chaim Weizmann, the first president of the State of Israel:
Whenever in a country the number of Jews reaches a certain level of saturation, that country reacts against them… Now, this reaction is not antisemitism in the ordinary or vulgar sense of the word, but a universal social and economic consequence of Jewish immigration; it is impossible to ignore it.[2]
“It seemed to me,” writes Bernard Lazare, the Jewish author of the book Antisemitism, its History and Causes,
that an opinion as universal as antisemitism, having flourished in all places and at all times, before the Christian era and after, in Alexandria, Rome, Antioch, Arabia, and Persia, in medieval and modern Europe, in a word, in all parts of the world where there have been and where there are Jews, it seemed to me that such an opinion could not be the result of a whim and a perpetual caprice, and that there must be deep and serious reasons for its blossoming and its permanence.[3]

I agree with everything in this article with one exception: I believe the author should have used the term Jewish Zionists instead of Jews. There are many Jews who do not hold to the principles of the Jewish Zionists. A few examples are Norm Finklestein, Aaron Mate, Gabor Mate, Katie Halper, Abbie Martin, and Max Blumenthal.
