The unifying concept among the tribe of Leftism, such as neo-Marxist, feminists, queer theorists, trans/non-binary, is that oppressed people of the world must unite, for they have nothing to lose but their chains, to paraphrase Marx and Engels in the closing of the Communist Manifesto (1848). This is the idea that there are no enemies to the Left. But we saw the first crack in this wall in the battle over trans and traditional feminists, in issues like women’ sports.
And now, as detailed at City-Journal.org, the division may be forever, as some Left groups are solidly in support of Hamas, and want to decolonise not just Israel, but all of the West as well. It is early days yet, but his division will be messy, and there will be no unified Leftist response as was seen during the heady days of the 1960s on university dream land.
