This week I had two conversations; one with a valued and respected friend and one with a total stranger. I found both of them profoundly disturbing. 

My friend is Jewish. In the course of a conversation over lunch he told me that he and his wife have decided to leave Britain if Jeremy Corbyn becomes our Prime Minister. Not to avoid the avalanche of new taxes to be expected from an authentically Marxist Labour government, but because he is afraid that the growth of anti-Semitism will at best go unchecked, and at worst be encouraged, by Corbyn's government.

Think about that for a second. One of Britain's best claims to be the most civilised nation in Europe is that there have been no pogroms here since that at York in 1190. I have never heard an anti-semitic remark from a British person in my life. I am sure we must have the occasional nut-job who harbours hatred for the Jews, but have never met one. Given that for a while, I was a partner in a predominantly Jewish law firm, I have had better than average chances of doing so.

I am proud of the fact that Britain has been for centuries one of the safest places in the world for a Jew to live. I was shocked to hear my friend express his fears.

This is no shrinking violet neither. He is a distinguished lawyer; a former partner in another City of London law firm. He has a fine mind, strong principles and a courageous, forthright character. He is a clear thinker and a tough negotiator. He is not a man to cut and run, so I do not dismiss his concerns at all. He is making a rational calculation. 

The second conversation was at my local petrol station. A well-dressed young black man driving a newish Audi accosted me as I refuelled Speranza. He felt I had cut him up at a nearby roundabout and had followed me to offer a critique. I don't believe his assessment was correct but let's pretend he was right because that doesn't affect my point. The conversation ran as follows (and I am rather proud that I stayed so calm);

"Do you know who a roundabout works?"

I think so, yes. Why do you ask?"

"You didn't give way to me back there"

"Really...?"

"As soon as I saw the car [pointing to Speranza, my Ferrari] I knew it would be driven by an ugly c**t and here you are"

"What did you call me?"

"You heard. An ugly c**t" [He then spelled the C word out, letter by letter]

"Charming"

"That thing [pointing to Speranza]. It's to replace a tiny d*ck. That's what it's for. Your d*ck is tiny"

As he turned to storm off, I finally lost it a little and called after him

"What kind of man speaks to a stranger like that, you uncultured bastard". 

His anger was genuine enough but it was not righteous. My impression was that I was the object of his hate not because of what I did but because of what he thought I was – rich, old "gammon". Outside the ranks of fundamentalist religions, only social justice warriors can behave so badly with such a righteous demeanour. This man was of the Left; consumed with envy and identarian anger.

Before you leap to a wrong conclusion, I an not seeking to join the identity politics jamboree. Far from it. The only "protected characteristic" I aspire to or recognise is "Human." Nor do I want legal protection from mere words. In the end, though I think he hoped I would offer violence so that he could beat me up, he did nothing but call me names. When I refused to rise to his bait (carefully calculating about how it would look on the petrol station's CCTV cameras, if I am totally honest) he walked away without converting his assault into battery.

He was throwing a tantrum like a spoiled child and a better come-back than I found in my distress would have been to laugh and ask him;

"What are you? 12!?"

What connects these two incidents apart from incivility and threat of violence? The politics of identity. An imperfect but, generally, safe country is becoming angry, violent and dangerous because the members of the British Left, in common with their comrades throughout the West, have deliberately fomented division. Their forerunners' attempts to turn class against class having comprehensively failed, they have spent the decades since the fall of the Berlin Wall (and some of them have spent far longer) trying to set race against race, sex against sex, faith against faith and so forth. That explains the anger of the young man with the Audi. He saw in me, not another human, but a category of oppressor. My driving error (real or imagined) gave him an excuse (as he would see it) to express his righteous contempt. His conduct was that of a medieval knight encountering – and expressing his scorn for – an actual villein; that is a person of an inferior class.

That, combined with the Left's quest for Muslim votes by its unholy alliance with Islam in support of the "Palestinians", accounts for my friend's calm assessment of the future for Jews on our sceptred isle. To them, he's not (as he truly is) one of the kindest, noblest and gentlest of men, but an enemy. A "Zio" to his face and God-knows-what behind his back, 

This post is not a counsel of despair. To be clear, I believe in the future of our country. To be even clearer, I don't accept the stereotyping of the "Millennials" and "Generation X'ers". I know enough of both to see through that. There are unpleasant and dangerous trends in Britain's public dialogue but I accept none of them as permanent. There are straws in the wind suggestive of public resistance to this vile brand of hate-driven, envy-driven, divisive and – yes – racist politics. But we are at a dangerous juncture in our national story and many more of us than already have need to take a stand.

We will be a poorer nation if my friend leaves. We will be a poorer nation if young Audi-man doesn't grow up to see the humanity in all of his fellow-Brits. It's up to every one of us to do our best to make this land of ours safe again.
