It has become clear in the last two years that the greatest moral challenge facing our Labour Party is not about policy. It is not about our continuing lack of power and the opportunity therein to rescue the nation. It is not even squarely about leadership.

No, the greatest moral challenge facing our Labour Party in 2017 is whether it is a place the Jewish people can call home. Can we confidently say that the Jewish people, against whom more grotesque crimes have been committed than against any other, have nothing to worry about and nothing to fear from the Labour Party?

Are we on their side? Will we stand with them in the face of the neo-fascism lately descending across the political scene throughout the Western world? Are we their advocates, their allies, their defenders and their comrades? Are we with them not tacitly and implicitly, but in the same full-throated voice with which we so roundly condemn the multitude of our political opponents?

And if we are not on their side, how can we claim to honour our ancestors, or the Labour Party they built? How can we claim to be members of a truly Socialist party when many among our number are apologists for, complacent about, and even advocates of antisemitism? The answer is that we cannot. We cannot claim to be a party of freedom and emancipation if we cannot call ourselves a safe harbour for a people who have been uniquely persecuted in the catalogue of human crimes.

Upon this ugly dilemma rests the moral uncertainty of the modern Labour Party, and every Socialist instinct it claims to hold. Power won by Labour while this malignancy lurks within is power won with a hideous, perhaps unbearable caveat. It has led some to question whether it is even worth winning it at all. Whether a Labour Party so morally compromised by its failure to deal with the antisemitism in its ranks is a party that will have the instincts, the strength and the credibility to govern in defence of Socialist ideals.

We owe those who have already left the Labour Party because they cannot bear the ordeal our continued resolve in the hope that they will one day return. That they will return to a party that can confidently claim in one voice not only that it is a place of refuge for all who suffer from the evils of discrimination, but that it is as inhospitable to bigots of all kinds as they would make it for the targets of their abuse.

Until we have driven this darkness out, little else matters. Truly. The soul of the Labour Party is at stake. And without a soul, a left-wing political party is no better than the forces of conservatism it dares to oppose. Without a soul, it is a mere agent of the nihilistic world view upon which its political opponents rest their designs. Without a soul, it is no longer the Labour Party we know and love.

This proudly Zionist website will continue to fight back. So too will the Jewish Labour Movement and many thousands of decent Labour members and supporters. There is no middle ground in this fight. No hiding place or refuge adorned with the comforting trappings of whataboutery. This is the greatest moral challenge facing the modern Labour Party. It is a challenge we cannot fail to meet.
