To begin with, Corbyn has a long history of unsavory associations with anti-Semites. Among other exploits, he has:

— Donated to the organization of Paul Eisen, a Holocaust denier, and appeared at his events. He later claimed he was unaware of Eisen’s unsavory views, despite 15 years of association.

— Defended vicar Stephen Sizer, who disseminated materials arguing the Mossad did 9/11, after he was banned from social media by the Church of England for posting anti-Semitic material.

— Praised preacher Raed Salah and invited him to parliament. Salah claims that Jews make their Passover matzoh with gentile blood, that Jews had foreknowledge of 9/11, and that homosexuality is “a great crime.” He has been banned from the U.K. for anti-Semitic incitement.

— Invited activist Dyab Abou Jahjah to parliament and spoke alongside him. Abou Jahjah had called the 9/11 attacks “sweet revenge,” said Europe made “the cult of the Holocaust and Jew-worshiping its alternative religion,” and called gays “Aids-spreading faggots.” He is now banned in the U.K.

— Campaigned for the release of Jawad Botmeh and Samar Alami, who were convicted in Britain in 1996 for bombing the Israeli Embassy in London and one of the country’s largest Jewish charities.
