I don't think the situation with the N-word is a double standard unless someone argues they should be able to use slurs directed at other groups while also saying that only black people should be able to use the N-word.
The concept of ingroups reclaiming slurs from outgroups is far from new. It has happened with women, LGBT people, and black people, among others. I don't see it as one of the problems with the subject of "offensive language" and excessively walking on eggshells.
I may have been a bit rushed when I wrote that last post, so please allow me to clarify.
I was addressing the general point about "language policing" as raised in the OP, or what was referred to as a "language-equity guide" used by various organizations. This also relates to numerous topics often associated with terms such as "woke" and "political correctness," so it all falls within the same basic category and the same mode of thinking - which is also often associated with identity politics.
It seems the whole idea behind it seems well-intentioned enough, so I have no quarrel with the motives or the intention. I find nothing wrong with a demand for basic politeness, courtesy, manners, or just overall human decency. If that's the sole basis and intention of PC language-policing, then I get it. I understand that. It's just basically an elaborate and grandiose way of sending the message "Let's all work and play nice together."
But do we really mean that? Has it really been working? Has American society actually gotten nicer and more decent over the past decades? I'm not just talking about politically incorrect language, but just general niceness. Are people more polite and well-mannered today than they were in days before political correctness? If not, why not? And if not, why are there those who keep insisting on doubling down on what appears to be a failed political strategy?
Based on what we see taking place in states like Florida and Tennessee, there are very serious and genuine concerns regarding setbacks and regression in the areas of civil rights and social justice.
Look at what's been going on for the past 5-10 years. Things are getting uglier and uglier out there, both on and off the internet. All the hullabaloo over Trump was really just a symptom of a deeper problem, but anyone with any kind of insight could have (and should have) seen this coming. I knew the country started heading in the wrong direction during the Reagan era. The left allowed itself become duped and co-opted by corporate slicksters. All this stuff about PC, "wokeness," language policing - it's Corporate America's way of making a parody and a mockery of civil rights. People see it as being silly because it IS silly. The left got totally hornswoggled, and now they've painted themselves into a corner.
It's not just about ethnic or racial slurs, although I picked that example because it's one that's come up recently, such as a teacher being fired for reading it out of a book, or a kid being attacked on social media for singing rap lyrics containing the n-word. The thing is, we all live together in the same society, intermingling and interspersing with each other's culture, which I regard as a good thing. The language and slang tend to flow naturally, and not everyone can think of the rules they're supposed to follow at any given time.
But my basic point here is that, if we are going to impose rules and police language to such a degree, then it should conform to a consistent set of principles, rather than just imposed in a random, ad hoc style. Worse still, it shouldn't be one set of rules for whites and a different set of rules for blacks. If people embrace that idea and think that it's okay, can they not see where it could potentially lead?
