If someone lays out sweeping edicts about prohibited behavior across a wide variety of different contexts and then refuses to explain or argue for them, then they shouldn't be surprised if they are not taken seriously. Maybe I missed it, but I have not seen any actual arguments in this thread as to why saying the n-word in the context of a quotation from a song is somehow commensurate to using it unprompted in a normal conversation. Are white people supposed to pretend the word doesn't exist? What purpose is that supposed to serve? If a white scholar were doing their doctorate in linguistics on the usage of the n-word, would you insist that never actually write or say the word? Why?
I have no problem with what Kendrick Lamar did in this context -- I can't say I'm convinced of the logic behind it but it was a respectful interaction. But the reactions in this thread are pretty damn inexplicable to me.
The explanation is that the word was and is a slur used against them by white people, and the act of reclaiming it necessitates disarming its utility as a slur, which means calling out white people using it. White people don't need to pretend it doesn't exist, they just need to be mindful that it isn't a word they have the social contract necessary to say it. It's actually not that alien a concept if you think about how people address others depending on certain preexisting relationships; I call my girlfriend "honey" but I wouldn't call my professor that. To simplify it further, the explanation is that when white people say the word, it is inexorably a slur thanks to the inescapable historical context of its usage.
The insistence that every argument on every subject be justified and laid out for the sake of debate is one that I sympathize with, but it is a belief that simply does not apply in every situation. People's lived experiences, in particular the lived experiences of marginalized peoples, matter
a lot, and frankly there are going to be areas related to life experience that are unknowable to the people who don't also share that life experience. Just the day-to-day existence of being black, or trans, or gay, or a woman, or a Muslism, etc. is something that deserves consideration and respect, and is going to entail having access to knowledge gained from that day-to-day existence that a straight white guy, for example, will simply never truly understand. So when a topic related to those lived experiences comes into play, like the usage of a slur like the n-word in a non-reclaimed context, trying to argue over it without considering the lived experience of the people at play is not only disrespectful, it's incorrect. A person of color saying "Don't say the n-word" actually is all the explanation they need to give, because there is no burden for them to explain their lived experience with that word for people out of the know; the context of them being black and making the request should really be enough. Anyone willing to go that extra mile and go into greater detail is doing you and everyone else a courtesy, honestly.
To use an analogy, if you entered a circle of friends where one of them was referred to by a nickname, and they asked you to call you by that nickname, I'd doubt you'd go to the mat over where/how/why they get a nickname and you don't, why you should get one, go over hypotheticals of when you could or should use their real name, etc. You'd probably just accept it and say "Okay."
