It's all a bit 'he who shall not be named' for me personally.
No it's not, that's a false equivalence. Ppl didn't use the name Voldemort out of fear, however the most 'righteous' character (Dumbledore) refused to cave to that fear & did use it.
It's more akin to 'mudblood'.
Courts/factfinding etc
do you think the original employment tribunal judge was wrong to use the full words when quoting what Carl said?
I suspect the rules in tribunals are different. But I've never been in one.
do you really think courts say 'n word' when it comes up in cases involving racial abuse etc? I've worked in courts and sometimes people feel reluctant to use 'bad' words but it's essential to have clarity.
Again, having never been in court I couldn't tell you, however I imagine social norms are put aside. These questions are a bit strawmanny.
Literature and the arts
If I were to write a book/play about how black slaves were treated in the USA, then sanitising it by moderating language would surely be misleading and minimises the hell that slaves went through.
If you're white (I've no idea) you're probably not making this decision without input from the people affected. Much in the same way as a man living as a woman can't talk on what it's like to live as an actual woman, neither can a white person truly write about racism from anything other than an academic or 3rd person perspective.
I don't think it should be illegal to use it, we should just be better than that. If I heard it being used in malice I wouldn't think 'you should be in prison' I'd think that person was a prick & I'd likely tell them so.
I don't think the word should disappear but I do think that in time it will just be another word, though not likely in our lifetimes.
