The boards have been full for a week with cries of woe that you can't criticise Israel without being accused of antisemitism. So to make life easy, below is a summary of what defines antisemitism as agreed by more or less the leading experts in the world. If you'd like to discuss Israel without being antisemitic, you can follow these guidelines to say what you would like to say without causing pain to Jewish people:
POINT 1
What is particular in classic antisemitism is the idea that Jews are linked to the forces of evil. This stands at the core of many anti-Jewish fantasies, such as the idea of a Jewish conspiracy in which “the Jews” possess hidden power that they use to promote their own collective agenda at the expense of other people. This linkage between Jews and evil continues in the present: in the fantasy that “the Jews” control governments with a “hidden hand,” that they own the banks, control the media, act as “a state within a state.
Making mendacious, dehumanizing, demonizing, or stereotypical allegations about Jews as such or the power of Jews as collective — such as, especially but not exclusively, the myth about a world Jewish conspiracy or of Jews controlling the media, economy, government or other societal institutions.
So when you're criticising Israel, please do so without implying Jews, Israel or anything relating to Jews is part of a plot to control things or act in evil ways generally or that Jews or any Jewish organisation have control over institutions. This isn't how other countries are spoken about and it's particularly antisemitic in line with Nazi propaganda.
POINT 2
Antisemitism can be manifested in words, visual images, and deeds. Examples of antisemitic words include utterances that all Jews are wealthy, inherently stingy, or unpatriotic. In antisemitic caricatures, Jews are often depicted as grotesque, with big noses and associated with wealth
This is one most people instinctively know is racist - to apply certain characteristics to Jews - like having lots of money or big noses etc.
POINT 3
Antisemitism can be direct or indirect, explicit or coded. For example, “The Rothschilds control the world” is a coded statement about the alleged power of “the Jews” over banks and international finance. Similarly, portraying Israel as the ultimate evil or grossly exaggerating its actual influence can be a coded way of racializing and stigmatizing Jews. In many cases, identifying coded speech is a matter of context and judgement, taking account of these guidelines
This means, don't be antisemitic when using any words which clearly refer to Jews in particular. "Jews own the banks" is antisemitic. It remains antisemitic when you substitute words, like "The Israel lobby owns the banks" or "Zionists own the banks" or "George Soros owns the banks". Substituting code words is not a free pass for being antisemitic.
POINT 4
Denying or minimizing the Holocaust
A pretty obvious one which needs no explanation.
POINT 5
Applying the symbols, images and negative stereotypes of classical antisemitism to the State of Israel
So this means taking classic antisemitic tropes or canards, such as "The Jews are puppet masters" and applying the same language to the only Jewish state. We see right through this, please don't do it!
POINT 6
Requiring people, because they are Jewish, publicly to condemn Israel or Zionism (for example, at a political meeting)
This means making a Jewish person, anywhere, anytime feel obligated, pressured or required in any way to condemn Israel or Zionism. It means you don't "put them on the spot" in public by singling them out as a Jew to ask their opinions on Israel's atrocities. Their views of these things will be coloured by a completely different perspective to yours, and likely more personal knowledge, their family history and so on - so please be respectful of their right to determine their Jewish identity and opinions without your critique.
POINT 7
Calling for, aiding, or justifying the killing or harming of Jews in the name of a radical ideology or an extremist view of religion
Another one which should be obvious, but clearly "gas the Jews" is unacceptable.
POINT 8
Accusing Jews as a people of being responsible for real or imagined wrongdoing committed by a single Jewish person or group, or even for acts committed by non-Jews
Again, fairly obvious.
POINT 9
Accusing Jewish citizens of being more loyal to Israel, or to the alleged priorities of Jews worldwide, than to the interests of their own nations
This is a common form of prejudice in Britain where Jews are frequently accused of being in on some plot with Israel, or part of a group of Jews acting against their own country for the benefit of Israel. It's madness, and please don't do it.
POINT 10
Denying the Jewish people their right to self-determination, e.g., by claiming that the existence of a State of Israel is a racist endeavor
Jews, like everyone else, have a right to self-determination. If you don't make other countries feel ashamed of existing or if you don't make other groups feel ashamed of their national identity; then Jews should be entitled to the same. You are free to have your own opinion on if Israel should be a country or not, and how it should be. You are not free to deny Jews the right to decide that for themselves though.
POINT 11
Applying double standards by requiring of Israel a behavior not expected or demanded of any other democratic nation
Another very common one, where Israel is often held to a very different standard to other countries. An allowance can be made for the fact surrounding countries generally aren't democracies and as such are generally held to a different standard, but you should aim to treat Israel in the same, balanced way that you would treat any other country.
POINT 12
Drawing comparisons of contemporary Israeli policy to that of the Nazis
This is another very common one. Do not compare things which are incomparable just for the sake of hyperbole. It's very offensive. Almost every Jew in existence lost family in the Shoah. Please don't use it to attack.
Those are the things you can't do. What you can do is criticise Israel robustly, like you would any other country
