Oh boy, where to begin?
How about his sponsorship in the 1980s of a group called the ‘Labour Movement Campaign for Palestine’. This fact is illuminating and horrifying because this group proclaimed in their materials from 1984 that it sought nothing less than “to eradicate Zionism.” That means the destruction of Israel, a country of 9 million Israeli Jews and Israeli Arabs. Antisemitism manifests itself, in part, by denying to Jews their collective right to self-determination under international law. That is why the views of this particular group (that Corbyn championed) is an example within the IHRA definition. So for years, he was active in an organization that, just like Hamas and Hezbollah and Iran, proclaimed the goal of ending Israel.
He aligns himself with organisations that promote a biased and simplistic approach to the complex Israeli-Palestinian conflict (e.g. BDS), and present this dispute over territorial and nationalist claims as the fault of only one party – Israel. Israelis want to make peace with the Palestinians. The harsh rhetoric of Corbyn and his associates ignores the support of the Israeli public for a two-state solution and past efforts of the Israeli government to promote negotiations and improve the situation on the ground for Palestinians, and overlooks the Palestinian’s leaderships intransigence and violence. Efforts to delegitimize, punish or isolate Israel (basically Corbyn’s life’s work) undermine this commitment. The Israeli-Palestinian conflict is complex. Holding Israel alone accountable for the conflict, as Corbyn consistently does, is inaccurate and unhelpful. The conflict over land and security can only be resolved at the negotiating table and through a two-state solution and both sides will be required to make difficult decisions and concessions. Corbyn’s approach to this issue by endlessly criticising Israel - all the while saying far less about the many other countries which have far worse human rights records - is not helping the Palestinian cause, quite the opposite. It harms it.
The event that places Corbyn well beyond the pale took place in October 2014. He went to Tunisia to attend a one-day conference attended by Palestinian groups, including representatives of known terrorist groups and left a wreath at the grave of a known terrorist (see photographic evidence proving this to be the case). Although Corbyn claimed it was a conference to "further the peace process", the title of the conference was "International Conference on Monitoring the Palestinian Political and Legal Situation in the Light of Israeli Aggression" (he is economical with the truth, basically).
Then there was the time he appeared on Iran State sponsored TV Channel, Press TV (and was paid 18K to do so) and when asked about a terrorist attack on the Egyptian border during Ramadan that had killed Egyptian troops replied "I see the hand of Israel." A British MP, peddling conspiracy theories on matters in the Middle East is not a good look).
In 2007, Raed Salah was jailed for 'blood libel' (racial incitement). Later in 2012, Corbyn referred to him as a "very honoured citizen" whose "voice must be heard".
When Corbyn spoke at a Palestine Solidarity Campaign meeting in 2008 he waited on stage for a speaker, Ismail Patel, to finish his speech. The speaker indulged in an attack on "Zionism" saying it made Jews "immoral in justice". Mr Corbyn didn't leave the stage and not be associated with this antisemitic rant, instead, as he passed Mr Patel, he patted his arm in a "Well done!" gesture (there’s video footage of this).
There are many, many more examples of Corbyn’s blatant antisemitism, but here are some of the most egregious ones. Is it any wonder then that as soon as he became leader of the party there was an influx of new members - holocaust deniers and holocaust minimisers - that, for some reason or another, now felt very at home in a social Democratic Party under his leadership?
He’s a hateful person.
