Here is a recent Intelligence Squared debate about Israel in which the pro-Israel side loses badly. The problem here is that the motion on the floor is whether anti-Zionism is a form of anti-Semitism. Clearly, it is at least hypothetically possible to sincerely oppose Israel without being an anti-Semite. The pro-Israel speakers, Melanie Phillips and Einat Wilf, never adequately address this issue. What they try to do is argue that anti-Zionism itself, as an ideology, is anti-Semitic even if not all anti-Zionists are themselves anti-Semites; such people simply fail to fully understand their own beliefs.
To make things worse, we have Mehdi Hasan in the opposition. Hassan’s chief strength is that he is a Muslim who is clearly not an Anti-Semite despite being opposed to Israel. He understands that there are lines not to cross and he acknowledges that many people on his side cross this line. Paired with Ilan Pappe, whose Jewish identity allows him to be the rabid one, Hasan gets to sit back and be the "moderate," assuring the audience that opposing the Israeli government and even wanting to replace it with a secular Jewish-Palestinian State does not make someone an anti-Semite. Perhaps I am too easy on Hasan due to my dismally low expectations for Muslims when it comes to anti-Semitism. The fact that he does not foam at the mouth is so surprising as to make him a model of reasonableness.
And this leads to one of the reasons why anti-Zionism, in practice, is anti-Semitism. What I never cease to find so shocking about the anti-Zionist movement is the extent that they do not even bother to seriously pretend that they are about anything other than killing Jews. This is different from the contemporary liberal discourse on hate speech where anything said by anyone who is not part of the "woke" set will be interpreted as hateful through a series of increasingly arcane hermeneutics even if it was perfectly acceptable even for Democratic politicians to say the exact same thing just a few years ago.
I am not asking anyone to be on board with Netanyahu or like Zionism. You do not even have to be an expert on Jewish thought or what bothers Jewish activists. All I am asking is that you do not say things that used to be obvious, only a few years ago, that you should not say. I am reminded of the Simpson's episode in which Sideshow Bob is able to be released from prison despite having tattooed "Die Bart Die" onto his chest.
This also is a reason to focus on leftist anti-Semitism, which tends to operate under the banner of anti-Zionism, as opposed to right-wing anti-Semitism even though both are legitimate threats. I expect people on the left to have absorbed political correctness and with it a certain caution with how their words might be interpreted by others. With conservatives, there is much more room to interpret them charitably as speaking in anger. If someone from the left says something that implies murder, they should be taken with complete literalness.
Let us acknowledge two non-contradictory truths. Palestinians have good reasons to not be happy with Israel and even have plausible justifications to use violence. That being said, anti-Zionism, despite its theoretical merits, has come to serve as cover for killing Jews. To be clear, our concern is not people who dislike Jews or say politically incorrect things but people who are actively trying to get Jews killed.
One might argue that when we are dealing with plots to kill Jews we should only focus on those who are literally firing rockets at us or trying to stab us. The reality is that the justification for mass murder is part of the action itself. For this reason, not even J. S. Mill thought speakers egging on angry mobs were protected by free speech. We have the example of Julius Streicher, the editor of the Nazi tabloid Der Sturmer. He was hanged at Nuremberg as a conspirator in Nazi crimes despite the fact that he never was in a position to order anyone killed. The Holocaust required the propaganda efforts of people like Streicher. Thus, he was not a martyr to free speech but a mass murderer as guilty as the people who ran concentration camps.
By this logic, we should not treat apologists for Palestinian terrorism as morally any different from the terrorists themselves. If you call for "Zionists" to be murdered and people kill Jews, you have entered into a conspiracy to murder Jews. It does not matter if you are not a Hamas officer and have never been in contact with them. You have helped to create an environment in which terrorists have reason to believe that their actions will not harm their cause. This makes it more likely that attacks will happen. Thus, you are an enabler of terrorism. If we allow either the enabler or the terrorist to operate freely Jews will die.
So what about the honest anti-Zionists out there like Mahdi Hasan? Ideas do not exist in a vacuum. There can be ideas tainted by their historical associations and the people who use them. For example, I believe that making voters pass a civics test could be a positive reform and would support it in any country besides the United States. In this country, literacy tests for voting played an important role in segregation. That history cannot be pushed under the rug. This thinking extends to conservatives and libertarians who wish to talk about state rights. It can be done but you have to be careful.
Let us be clear, this is not the genetic fallacy. I am not saying that tests for voting are bad because of their racist past nor am I suggesting that all people who support them are racists. (Again, I think, in theory, they might be a good idea.) That being said, it is reasonable for blacks to be on the lookout for people who wish to kill them. If the only way you can think to reform elections is through voter tests then it is a signal that you are not a friend of the black community. It does not matter if this is true or not. Blacks would still be justified, as a practical matter of self-defense, in treating you as if you had entered into a plot to lynch them.
Similarly, I would argue that, once we admit that there are anti-Zionists who wish to kill Jews and that these people are more than just a fringe element of the movement, at a certain point the whole concept of anti-Zionism becomes tainted. It reaches the point where, even though a person accepts the essential argument of anti-Zionism as a theory, operating a non anti-Semitic anti-Zionist movement becomes almost impossible.
Every movement, whether libertarianism or anti-Zionism, had its share of deplorables. The key issue is whether it is possible to disassociate oneself from them. This means that you do not praise them, you do not share a platform and do not act in a way that benefits them. For example, as a libertarian, I have disassociated myself from Ron Paul and the Rothbardian wing of the movement because they are tainted by racism and anti-Semitism. This is the case even though I mostly agree with them in terms of policies. It is not even that I think such people are necessarily bigots. Defending them, even though intellectually doable, simply distracts from the legitimate libertarian message of transcending the right and left partisan divide to open our borders and cut government spending on the drug war at home and nation-building abroad.
We might imagine our non anti-Semitic anti-Zionist spending months organizing a rally to denounce Israel’s blockade of Gaza. You better screen the speakers. It is ok if some of them have made inappropriate remarks in the past as long as no one has been party to murder either directly or rhetorically. You want to memorialize Palestinians killed by Israel; fine, just as long as you make sure those people were not members of terrorist organizations. And if Hamas or Islamic Jihad start launching rockets the day before the rally, you need to cancel it. Anything less and you can no longer Pontius Pilate yourself. You are a party to a conspiracy to kill Jews.
In a similar fashion, terms that may be innocuous by themselves can become tainted. Take the terms, for example, "intifada," "jihad," and "from the river to the sea, Palestine shall be free."
While it is possible to use these terms in ways that do not imply violence. Since they have become code words for violence, you do not get to claim your own particular understanding of the term. You use these terms and I have the right to assume, as a matter of self-defense, that you are plotting to kill Jews.
In this matter, it is important to bend over backward to demonstrate non-hostile intent. Remember that it is your enemies judging you. As a Jew and the grandchild of Holocaust survivors, I am not obligated to wait until I am completely sure that you are plotting to kill me. If you choose to call me a Nazi and cooperate with people who are trying to kill me I will assume that you are trying to kill me and wash my hands of any responsibility for your blood.
