@OtterlyAstounding The BBC article you posted earlier is good and expresses a few things I've been trying to say:
"It's the filthiest, dirtiest, nastiest word in the English language." - Christopher Darden, prosecutor in the OJ Simpson trial
"It's actually probably the most offensive word in English," - David Lammy
Dr Stanford says white people cannot use the word because its origin in slavery hasn't been lost.
"These are people who have created the word in the first place, but who have now lost power in relation to it, they have lost the power to use it with impunity, they have lost the power to reclaim it."
Prof Andrews adds: "If you understand the history of the word and how it's been used, it's not for white people to use, it's not for anybody else to use.
"If you look at the way that we use the word, which would be more acceptable - and I'm not saying I'm pro using it - it's about endearment, it's about family, it's about connections, it's about recognising the situation that we're in.
"So if you're not black you can't do that. You actually can't use the word in the way that we use it. It's not possible, because you're not in that space. So any other usage of it is completely wrong."

The thing I found most surprising in that article is that the BBC were defending the use of the full word in a news report about a racially aggravated attack as recently as 2020. In fact it was the very same month in which Mr Stevenson used it in the training session which led to his dismissal.
