This comes from Marc Lamont Hill, courtesy of an intrepid online researcher of antisemitism. Hill had previously gotten into trouble for combining his CNN gig with support for murdering Jews. But even though CNN parted ways with him, the Democratic Socialists of America (DSA) are always happy to give an antisemites a forum, whether it's Corbyn's rep or Hill.
In 2014, Hill had claimed on CNN that the kidnapping and murder of three Jewish teens, Naftali Frenkel, Gilad Shaer, and Eyal Yifrah, one of them an American citizen, wasn't "terrorism", but "resistance".
Earlier this year, Hill had insisted that "occupied people have a legal and moral right to defend themselves" and that the idea that Israel has a "right to exist" is "propaganda". In May of last year, he had argued that Trump's "call for Palestine to 'reject hatred and terrorism' is offensive."
"We have allowed this nonviolent thing to become so normative that we're undermining our own ability to resist in real robust ways," he complained.
A month after the Pittsburgh massacre, Marc Lamont Hill addressed a UN event in support of the terror colonialists occupying parts of Israel, endorsed BDS, called for the destruction of Israel and justified the murder of Jews.
"We must recognize the right of an occupied people to defend themselves. We must prioritize peace, but we must not romanticize or fetishize it. We must promote nonviolence at every opportunity but cannot endorse narrow politics that shames Palestinians for resisting," Hill argued.
John Perazzo has more background on Hill's hate here.
Hill professes to have once belonged to an organization known as the Ansaaru Allah Community, an Islamic sect whose doctrines resemble those of the racist, black-supremacist Nation of Islam. On his publicly available Curriculum Vitae, Hill proudly includes a lecture on "The Importance of Ideological Training in the New Millennium," which he delivered at the Polymathematic University in Pennsylvania – a self-described "revolutionary center for the training and development of professional revolutionaries." The event was sponsored by the "Poor Righteous Communist Party," a Maoist group that seeks to develop "an ever glorious Righteous Communism."
Hill has an extensive history of anti-Israel activism and this fits in neatly with it. But it also defines the underlying agenda for the black nationalist movement.
