Thanks to Corbyn, the Labour party is expanding, attracting many leftists who would previously have rejected it or been rejected by it. Among those are people with hostile views of Jews. Two of them have been kicked out, but only after they had first been readmitted and once their cases attracted unwelcome external scrutiny.
The question for Labour now is whether any of this matters. To those at the top, maybe it doesn’t. But it feels like a painful loss to a small community that once looked to Labour as its natural home – and which is fast reaching the glum conclusion that Labour has become a cold house for Jews.

Prewar Jews, like today's East End Muslims, also lived in unforgiving poverty. They too were herded into the cramped streets of East London as the first stop for new immigrants. They too were reviled as outsiders, branded as parasites on the indigenous society. And they too were feared as a potential fifth column, suspected adherents of a violent, supranational ideology. The "Jewish menace" was said to be first anarchism and then Bolshevism. Today's "Muslim peril" is jihadism.
This is what grieved some of those mourners most. As they huddled together in fear, one spoke for all when she said: "This is so wrong. We should be on the same side."

This poses its own danger for democracy. Because there can be no collective decision-making – which is what democracy amounts to – without a collective, agreed-upon basis of facts. If we can’t first agree that the house is on fire, we can’t begin to talk about putting out the flames.
