While still a fan of Tarantino's work (I did draw a line at Once Upon A Time in Hollywood, as his take on my childhood hero, Bruce Lee, was a bridge too far for me), I recognize that QT takes full advantage of his position in this quasi-exploitive power dynamic.
He does it with the exploration of his creepy foot fetish in much the same way he has exploited the loophole that white (male) privilege has afforded him to indulge his childish, fetishistic need to repeatedly make use of the 'N' word.
Some years ago, I read an interview in which Spike Lee recounts a conversation he had with Harvey Weinstein of Miramax, I believe. He was expressing his frustration with Tarantino’s free reign to use America’s favorite anti-black slur. But when he posed the question of whether he’d be able to do the same in a film with repeated use of a slur that's used against Jews, the answer was a very prompt ’no.’
No surprise there.
Conversely, even in the film Inglorious Basterds, although ethnic bigotry was conveyed in the film’s dialog in various ways, none of the known slurs against Jewish people managed to appear. This fact would seem to be incongruous with the dehumanizing evils of Nazi Germany and only further illuminated the down-punching dynamic that QT was free to have fun with.
