After another weekend of trouble across the world sparked by the killing of George Floyd in police custody in the US, an expert group advising the Stormont Executive has suggested that Northern Ireland be made a "racism-free zone" in an effort to tackle racial inequality.
At first glance it sounds tokenistic. Slogans won't stop ethnic minority families being hounded out of their homes in Belfast.
That will only happen as part of a genuine collective effort to make Northern Ireland less of a cold house for those who aren't originally from here, and that's so far down the list of priorities up on the Hill that it barely registers.
In a way sectarianism has simply allowed local politicians to shrug off the problem of racism by pretending that people here are too busy fighting each other to have the time or energy to devote to other forms of bigotry.
That's not how racism works. Just as a job expands to fill the time to complete it, there's always room for a little bit more hatred.
Pastor Barrie Halliday's call for Black Lives Matter supporters to "go back home if you think we're so bad" exposes how disturbingly close those primitive instincts still lie to the surface.
The 52-year-old from Co Armagh has now been arrested and charged with misuse of a public electronic communications network, namely Facebook, and is due to appear in court next month. It's up to the Director of Public Prosecutions what happens next.
Regardless of the legal rights and wrongs of the case, it should never be anything less than shocking to hear a man who calls himself a Christian take to social media and tell people in this country that "it may have been boats that brought you here three or four hundred years ago and you were brought under duress and against your will, but there's boats sitting there empty at the minute doing nothing and you're welcome to get on them".
It's also bizarre. Who exactly was Mr Halliday talking about?
The bit referring to people being brought on ships against their will only makes sense as a reference to slavery, but most BAME (Black, Asian, minority ethnic) people in the UK are not even descended from slaves, so where exactly is "back home" for them?
Somali woman Sahra Mahamuud asked that question last month after being driven from her home in the Village by a loyalist paramilitary-backed campaign of intimidation.
She said her children didn't even understand what it meant when told to "get back where they came from" because they were born in the UK.
This already is where they're from.
Even more perplexing is Halliday's apparent failure to appreciate that there are indeed people here descended from those who came in boats three or four hundred years ago - and he presumably is one of them.
Is he saying that Ulster Protestants from Plantation stock don't belong here either?
The accusation that they should "go back home" has been thrown at Protestants in Ulster for centuries.
Regrettably, those attitudes still persist.
A video taken during a concert at the Ardoyne Fleadh in 2014 showed the lead singer of a so-called rebel band telling the crowd it was time that soldiers and their "Orange comrades" all "f***** off back to England".
The organisers of the event apologised unreservedly and the singer insisted that his remarks had been "taken out of context" - as if any context would have made them less objectionable.
The bigotry goes the other way, too.
Catholics in Glasgow have regularly been targeted by football chants and graffiti that says "the Famine is over, it's time to go home".
The TV show The Empire Laughs Back once featured a sketch between comedians Kevin McAleer and John Byrne playing respective bigots, which brilliantly satirised these competing views of the past.
It begins with McAleer declaring that Protestants "robbed the Catholic land" and "drove us up to the hills like so many sheep".
"I couldn't have put that better myself," replies Byrne.
"These early settlers were fine, decent, hard-working Protestant stock. What did they find when they got here? They found a wasteland; a bog, as Kevin said. They built towns, they built cities, they started up industries. Basically, they transformed Ulster into the garden that we have today."
The sketch would probably be considered too offensive for broadcast at a time now when even Fawlty Towers has been dragged into the culture wars, but it remains funny because that is how many people here still think.
Real history is too complicated to be reduced to a simple matter of good natives and bad invaders. Writing in his personal blog a few years ago Mark Thompson, a former chair of the Ulster-Scots Agency, observed how, for successive generations after they first arrived in the north of Ireland, the majority of Protestants, like the majority of Catholics, were poor, landless labourers with few rights.
They were oppressed, too. Most didn't own houses or land until very recent decades.
In an amusing aside, he even recalled that it was the Gaelic O'Neill clan that at one time invited over their Scottish cousins the Bruces, together with 15,000 of their men.
Only 300 stayed permanently, but presumably their descendants are still around today. "If you're uptight about people of Scottish descent living here, take it out on the O'Neills. They invited us - twice," Thompson quipped.
That's what makes it strange when those who've been on the receiving end of sectarian jibes from both sides down the years refuse to recognise the same prejudice when it's used to say black and Asian people have no right to be in the UK, including Northern Ireland.
Nowadays republicans are more likely to tell unionists that they should stop being silly and accept that they're Irish, rather than that they should "go back home"; but it's just a more subtle form of bigotry, which now finds a revolting echo in what Pastor Halliday said to supporters of Black Lives Matter.
To demand that minorities in Northern Ireland, whether they're black, Polish, Chinese, or any other, should simply be grateful for what they're given and not complain about the imperfections in the society they live in is no different, and certainly no better, than Kevin McAleer's fictional nationalist bigot telling Protestants to "knuckle down and turn Catholic like the rest of us" and "enjoy themselves for once in their lives".
The message is the same: fit in or get out.
If an Ulster Protestant won't accept the right of people to an equal place in a country after years of living there, who will?
Go back far enough and we're all from somewhere else.
