Your answer to the last ask, I think it's a good idea to set a story like that in another world. I wanted to add that if your story is set in a fantasy world that shows racial diversity (and that's rare), using real world slurs is both offensive to your readers and lazy writing. It's a fantasy world. What are the odds your characters speak English? Make up slurs based in the languages THEY speak. I swear if I read another fantasy story where Black characters are called the n-word, I will scream.
BRHood: I didn’t know that was a thing in fantasies. Wow. That’s really shitty and just lazy writing. I agree with you completely.
