UK left needs to do introspection on antisemitism. There's considerable resistance to doing so. There's an obvious temptation to deny, downplay, or wish it somehow goes away by itself. There's an obvious temptation to "contextualise", show that others are worse 1/
But this won't go away by itself. And any public intervention on this issue from the left that does not acknowledge the need for introspection, is counter productive. Whether intentionally or not, it supports the denialist/downplaying narrative. 2/
Without introspection, people will continue thinking in terms of "bad apples". They will continue thinking of antisemitism as an external problem that somehow, strangely, inexplicably, emerged in the Labour party, rather than a systemic and internal issue. 3/
Having lost control over the Labour party, the left feels under siege and is generally in no mood for introspection. And perhaps that's not surprising. But without self-reflection, there's a high risk that these patterns will continue to be reproduced. 4/
I'm saying this as someone who is invested intellectually and political in the left (though not in the sense of electoral politics). But I also doubt if saying these things helps, given the toxicity of the conversation. And surely the immediacy of this medium doesn't help.
