This word is relatively unique. The most affective swear words are effective not because of their meaning but their sound.
ShiT
CunT
FUCK
WANKer
TWaT
The meaning is irrelevant, it's the structure of the word that makes it powerful (& satisfying!!)
The most similar sounding word we use in English in terms of 'mouth feel' is
bugger
which is rarely if ever used as an insult, it's affectionate despite having a much darker meaning. It's the sound that makes it cutesy.
So the N word should fall into a similar category if you look at it in the same way we use other offensive words - but it doesn't.
It's ALL about the meaning, every last syllable & every time it's spoken by someone who isn't black & every single one of us knows that! I couldn't say it alone to myself (in what possible context would I use it?!), I don't want to. It's a disgusting & repellent word.
I'm by no means a SJW by today's standards, neither could I be called 'woke' by the same measure, but this word crosses every boundary I was brought up with & for very good reason.
It's STILL used as an insult, it's still a symbol of racism. When that stops, and it's just a bunch of letters then sure, let's revisit this.
