I have already indicated that I believe antisemitism to be essentially a neurosis, but of course it has its rationalisations, which are sincerely believed in and are partly true. The rationalisation put forward by the common man is that the Jew is an exploiter.

What does the strange irrational hatred called antisemitism consist of? I am not a historian of this vast topic, but personally I define it as the theory that holds Jews responsible for the spilling of the blood of non-Jews.

[...] antisemitism is rationalised by saying that the Jew is a person who spreads disaffection and weakens national morale.

Antisemitism based on purely emotional grounds will always find its ultimate expression in the form of pogroms. A rational antisemitism, however, must lead to the systematic legal fight against and the elimination of the prerogatives of the Jew. ... Its ultimate goal, however, must unalterably be the elimination of the Jews altogether.

As for the Jews, their explanation of anti-Semitism is more characteristic yet. In addition to the usual cliche, "with hatred and savagery" - naturally with no motive, they do not care to discuss motives - according to them, anti-Semitism is a madness, an intellectual degeneration, an affliction of the spirit.

Of all the bigotries that savage the human temper there is none so stupid as the anti-Semitic. It has no basis in reason; it is not rooted in faith; it aspires to no ideal; it is just one of those dank and unwholesome weeds that grow in the morass of racial hatred.

Antisemitism is an evil. It is a very specific type of racism, one that festers and spreads like an infection. Its conspiratorial nature attracts those who would have no truck with any other form of prejudice. Indeed, it can be those who call themselves "anti-racist" who are most blind to it. The reason the Equality and Human Rights Commission (EHRC) opened their investigation into the Labour Party was because it had become an incubator for this poison. We needed to change. That's why my first act as leader was to commit to tearing antisemitism out by the roots, without fear or favour.

The anti‐Semite has chosen hate because hate is a faith; at the outset he has chosen to devaluate words and reasons. How entirely at ease he feels as a result. How futile and frivolous discussions about the rights of the Jew appear to him. He has placed himself on other ground from the beginning. If out of courtesy he consents for a moment to defend his point of view, he lends himself but does not give himself. He tries simply to project his intuitive certainty onto the plane of discourse. I mentioned awhile back some remarks by anti‐Semites, all of them absurd: "I hate Jews because they make servants insubordinate, because a Jewish furrier robbed me, etc." Never believe that anti‐ Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti‐Semites have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past. It is not that they are afraid of being convinced. They fear only to appear ridiculous or to prejudice by their embarrassment their hope of winning over some third person to their side.

One key fact about contemporary antisemitism is that it must not be mentioned. Antiracists are educated to assume that talk about antisemitism is an indicator of a Zionist attempt to silence the oppressed Palestinians; it is mis­recognized as the mobilisation of Jewish victim­power, the playing of the Holocaust card. The left is not hostile to Jews when they are powerless and stateless; but it finds it hard to shake the idea that Jews are untrustworthy and are connected to money. The image today is that the Jews have managed to strike a bargain with the American and capitalist devil; instead of playing their role as the symbol of the oppressed, they are conceived of as having saved themselves at the expense of everybody else.

They charge us with antisemitism, The truth is, those hurling these charges harbor a 'passionate attachment' to a nation not our own that causes them to subordinate the interests of their own country and to act on an assumption that, somehow, what's good for Israel is good for America.

Yet one of the marks of antisemitism is an ability to believe stories that could not possibly be true.

Perhaps the greatest outrage in the Middle East is the way the Israelis have been treated in comparison with the Egyptians. That this has been allowed to pass with so little protest must, it seems to me, be due to the anti-Semitism, conscious or unconscious, which, unhappily, exists in so many circles. I personally hold no particular brief for the Jews. There are good and bad Jews, just as there are good and bad Englishmen, or even good and bad Scots; and, for all I know, the percentage of bad may be greater in one case than in the other. But whatever the facts, I consider indiscriminate anti-Semitism altogether deplorable. There is not even a difference of colour to explain this violent prejudice which crops up so often in such unexpected places. Whatever the reason, nobody can deny that bias has been shown in the way the Israeli-Egyptian conflict has been handled by the United Nations.

Anti-Semitism itself is a conspiracy theory... Anti-Semitism differs in this respect from racism, xenophobia, misogyny, and homophobia. Those other bigotries are founded on contempt. Anti-Semitism, like all forms of conspiracism, is founded on paranoia. Which is why people who start down any conspiracy-seeking path so often arrive at anti-Semitism. The pull is hard to resist, because the idea of Jews as arch-manipulators is such a powerful cultural resource.

And the venality of those Judaized is incapable of explaining anti-Semitism as a social phenomenon, we will call it the anti-Semitic theory.
