Well, Spooks was superb. Poor Tom has been sidelined tonight in favour of the charmless Adam. Damn.

Now, Keith. Here's the lowdown on antisemitism. Are you listening? Good!

1. Antisemitism is the expressed hatred of or threats towards Jews because they are Jews.

2. Antisemitism has nothing to do with criticism of the policies or activities of the Israeli regime. That includes activities such as ethnic cleansing in the Negev or illegal settlement building in the occupied West Bank, or the blatant discrimination against non-Jews, especially Arabs, in Israel, which I've catalogued on several previous occasions.

3. Antisemitism has nothing to do with BDS, which is an international campaign to put pressure on the right-wing ISRAELI REGIME to try to get it to stop discriminating against non-Jews in Israel, the occupied territories and Gaza.   

4. Antisemitism is a very unfortunate natural phenomenon. It is not subject to unnatural, false definitions favoured by blinkered pro-Israel factions. It's very simple. You are prejudiced against Jewish people purely because they are Jews. Nothing else. Nothing to do with countries or their policies.

5. Antisemitism has nothing to do with disagreeing that the state of Israel should have been founded. It is, however, antisemitic to declare that Israel should be wiped off the map, because, if you do, are calling for the destruction of or enforced mass emigration of millions of innocent Jewish people with family roots in Israel.

6. It is not antisemitic to say that you are anti-Zionist. Zionism is a highly political movement. It is not antisemitic to oppose the notion that Jews are entitled to a separate homeland. I hate to say it, and I'm very mindful of the Holocaust, but there is nothing particularly special about 21st century Jews that puts them on a different footing to 21st century anybody else. That isn't to say that Jews should not be treated with respect and with due regard for their distinct ethnicity, but that applies equally to many other groups as well.

7. There is endemic racism in the Catholic Church (apart from Wagner, quite possibly the most important peddler of antisemism in the last 150 years), the Church of England and the Tory party. Not to speak of overtly racist parties such as UKIP. Shockingly, there may be a small amount even in the Labour Party, but, if so, it is confined to a few people who may need a word in their shell-like to put them on the right path. There is a large faction within Labour who want to see Corbyn go. They have discovered that their best weapon is the trumped-up charge of. antisemitism in their ranks.
