Ah, the block list is going to go up a lot as I read this thread, I'm guessing.
If you aren't black, and you think you have a reason (or are trying to find one) where it's OK to say the N word in a non-academic context (and maybe even then), or you think you have a valid opinion on whether black folks should use it, or you think that black folks using it somehow justifies your use of it, you're either willfully ignorant of the depths to which that word has been used to dehumanize, and thus is indeed worthy of unique treatment, or you're a bigot, and likely both.
Edit: Not as many folks falling over themselves to find the corner case where it should be OK for them as I expected. gg fediverse, you aren't quite as shitty as r****t yet.
