Anti-Jewish hate is a staple of the far left’s world outlook per Oliver Kamm in The Jewish Chronicle

This https://www.thejc.com/comment/comment/anti-jewish-hate-is-a-staple-of-the-far-left-s-world-outlook-1.461702 is a must read article, yes another one about Jeremy Corbyn, the Labour Party and antisemitism, here's an extract:

'I'm sure Corbyn is sincere in his belief that he is a principled opponent of antisemitism. It just happens not to be true.

There are leftists from the generation of 1968, like Joshka Fischer — who went on to be German foreign minister 30 years later — who realised the descent of their comrades into traditional antisemitism and recoiled from it. Corbyn doesn't even recognise antisemitism when he is literally looking straight at it.'
