This was all already explained in Chasing Amy:
Hooper: Check this shit. You got cracker farm boy Luke Skywalker, Nazi poster boy, blond hair, blue eyes. And then you got Darth Vader, the blackest brother in the galaxy, Nubian god!
Banky Edwards: What's a "Nubian"?
Hooper: Shut the fuck up!
Hooper: For years in this industry, whenever an African American character, hero or villain, was introduced - usually by white artists and writers - they got slapped with racist names that singled them out as Negroes. Now, my book, "White-Hating Coon," don't have none of that bullshit. The hero's name is Maleekwa, and he's descended from the black tribe that established the first society on the planet, while all you European motherfuckers were hiding out in caves and shit, all terrified of the sun. He's a strong role model that a young black reader can look up to. Cause I'm here to tell you, the chickens is coming home to roost, y'all. The black man's no longer gonna play the minstrel in the realm of comics and sci-fi fantasy. We keepin it real, and we gonna get respect by any means necessary.
Holden: Ah, come on, that's a bunch of horse shit! Lando Calrissian was a black guy. You know, and he got to fly the Millennium Falcon, what's the matter with you?
Hooper: Who said that?
Holden: I did! Lando Calrissian is a strong role-model in the realm of science fiction/fantasy.
Hooper: Fuck Lando Calrissian! Uncle-Tom my pals!
