Why is the “N-word” held to such a high standard in comparison to other swear words?
Because societal taboos have changed in the West. Formerly, prurience was taboo and racism was commonplace. Now, prurience is commonplace and racism is taboo.
And that is not a value judgement. It’s just an observation. Just because something was a taboo doesn’t mean it was a bad thing. And just because something is a taboo doesn’t mean it is a good thing.
But then again, I share the modern rather than the older set of moral values. So I would say that.
