I love Tarantino films a lot but even I can admit that there is something going on there with how many times the N-word is used in his movies, regardless of the setting. He himself isn't racist, and Idk the made-up words dude is using in the video, but there definitely is something going on.
Django makes sense, though there was a bit of an overuse of it.
99 times in Django
39 times in Jackie Brown
16 in Pulp Fiction
5 in Reservoir Dogs
This is none of my business, but from a linguistic perspective the "N" word only means "black male/female" in Latin languages. Black as a name is translated into nigrum and the adjective is the "N" word. It's widely used in scientific names like one wild tomato species here known as Black nightshade (Solanum nigrum).
And for race there are 2 names for what's generalized as "blacks" in Africa in the Arabic language, one is Zinj which are the descendants of Ham (son of Noah) and Ahbash "Abyssinians" which are Semites "descendants of Sam son of Noah" that are in Eastern Africa like the Pharaohs. The illegal name here is calling someone a slave which you, at least, get fined 500 OMR ($1,300 USD) that goes to the victim.
