Don’t some Tarantino movies have several mentions of the word? And he’s still a Film Bro Favorite, so I doubt it.
I can’t think of a movie of his without the word! Django Unchained uses it 110 times! It’s just most of his movies take place in olden times or in a dirty crime world, so it’s not unexpected for the word to be used. I have seen people accuse Tarantino of being racist though.
