I reckon if you plonked a white man in the middle of Nigeria (as Froggy has mentioned) and across the road amongst a group of local black men was another white man, you'd refer to him as the white men.
That said, the official shouldn't have referred to the player by his skin colour. At the very least it's extremely unprofessional and asking for trouble in this current climate. Use his name, squad number, point him out, anything.
However, all of this has wound me up a little bit. I do think there are scenarios where a white person would be singled out and identified for his colour.
But given the nature of the world at the moment, the fact that there are actual racists mixed in with a minority of people who want to be outraged by everything and the virtue signallers, we have created this environment where people are petrified to even say the word "black".
A year or two ago, I worked with two lads, both called Lee. One white, one black. Another lad I worked with was telling me a story about "Lee", and he got flustered when I asked which one he meant. He began to describe his height, his job, where exactly he worked, everything on order to avoid saying "black". Is this the world we want to live in?
Obviously, things aren't as simple as I'm making out. Some sensitivity is required at certain times. But the ideal scenario, for me at least, is for skin colour to be seen as irrelevant as hair colour or eye colour. It's just another physical feature. Not malice, no intent, no judgement.
However, such is the way of the world now, there is a part of me that fears getting flamed for saying this, so let me caveat with...
The official was wrong. I'm mixed race (though you might not realise it to look at me), and I have experienced racist abuse. So there, you can't cancel me or sack me or whatever.
As a Nigerian, I can tell you for a fact that we'd refer to the skin colour and without fear of racism accusations. In fact, a common phrase for white people in Nigeria does refer to their pale skin. But that's the privilege Nigerians get living in their own land; and largely because we haven't had a history of oppressing white people in Nigeria, so no one is sensitive about it.
In the West, that's clearly different. And black people haven't ever been compensated for it (like for example the Jewish community were). So thus, what black people get is apologies and cancel culture. To be honest, it's pretty much the ONE privilege that black people have over white people in the West; the "race card" privilege when it comes to words (and the "penis" conversation). Is it fair that a black man can speak about race more freely than a white man without being accused of racism (unless you're Wiley)? No. But white people have traditionally held their own "race card" privilege in other areas of Western society; such as jobs, housing, loans, wealth etc.
Now I'm not one to care much for words, and unintentional or even casual racism. But some people do, and a lot. Some black people in the West do so, because it's the only thing they have that they can easily prove; it's easy to prove someone's words are racist; it's much harder to prove someone's action (denying of a loan/job/house/opportunity) as racist. True racists are people who act in a racist, bigoted, biased manner but navigate the words (unless they slip up unintentionally).
Thing is, we can all use racist words, without being racist. If you call me a black twat in a fit of anger. Should I be more concerned with the fact you called me black or a twat? Should I be saying you're racist because you should have just called me a twat? I think it's all about intention. The word "nigger" and "negro" is well known in *English/American culture* to be offensive and racist terminology, so to use it, would be to intentionally try to offend. Anyone born there, using that, racist or not, deserves the backlash coming to them if they do. But that's not the same in other European cultures.
Most black people really care about actions which are racist more than words anyway. Cancel culture is a white liberal thing, probably stemming from white liberal guilt.
I do find it a bit funny though that white conservative folk complain about fairness in terms of words, and how "what if a group of black men said X, Y and Z about a white man, it's not considered racist and that's not fair".. well yeah, duh, sure.. like I said, it's the one privilege a black person has in the West; that we can talk colour more freely than white people without fear of accused racism. Because, y'know, of all that unpaid, slavery that took place not too long ago.
Trust me, most black people would swap that one privilege over words if it meant they had better opportunities in other areas of society, and didn't HAVE to do things such as Google "what is the racism statistics in Spain/China/Liverpool/Leeds", every time I want to go on holiday/abroad/to a game.
