shitty sci fi writers: “they’re aliens so they aren’t politically correct and they say slurs!”
decent sci fi writers: “they’re aliens so they wouldn’t know human slurs in the first place”
good sci fi writers: *kicking the shit out of the shitty sci fi writers*
also “oh the translator is just translating it as a slur” argument…why would the translation software have the slurs in it?
god tier sci fi writers: a human says a slur, the translator says “this is a discriminatory term for humans with darker skin” and the aliens nod and then promptly beat the shit out of the human
