So nobody else thought it was racist that the cia officer wasn't allowed to talk, without the mountain king barking like a dog.
On this point specifically: I think that you are correct that director Ryan Coogler did choose to depict open racism in certain scenes. However, I think you missed something about these scenes -- it wasn't "
Black people gettin' back at the man!". Rather, in the
Black Panther world, open racism was used as a thinly-veiled proxy for ignorance.
M'Baku barked down Everett Ross for a few reasons. Ignorance of what Ross offered to the efforts against Killmonger. To assert control over his throne room in a way he could not with T'Challa. And, yes, to prove that he would not be cowed in his own court by a white man. Consider also that M'Baku was meant to represent an uncouth, unrefined character. M'Baku is not the moral compass of the film -- T'Challa is.
Another example of expressed racism marking ignorance is in Shuri's dismissive attitude towards both Everett Ross and Bucky Barnes. She may know a lot about tech and computers, but Shuri is young and ignorant -- especially ignorant of the bravery Ross would later display in the fight against KIllmonger's forces. The racism Coogler presents is not meant to elevate the racist characters into mini-heroes for getting back at white people -- it is meant to shine a light on their ignorance, and ultimately the ignorance that gives birth to all bigotry. If there was any doubt about Coogler's intended message, T'Challa's speech during the first in-credits scene lays bare the anti-divisiveness message.
Or how the Wakandans were sending weapons to London, Tokyo and somewhere else to fight the oppressed.
This was Wakandans under Killmonger's illegitimate leadership -- specifically what the heroes in the movie were fighting against.
Or how Killjoy would rather die than be held in bondage.
In the context of the film, this is a reasonable choice for Killmonger to make. For one, Killmonger is known to viewers to be (regrettably) damaged goods -- he is not seeking the redemption T'Challa is offering. For another, many black people raised in poverty in the U.S. will have allusions of slavery in their minds when faced with impending bondage.
Plenty more but gtfo if you didn't think any of that crap isn't racist. The whole movie was over the top racist.
I agree with you that racism is depicted in the film. I don't think we agree on why Coogler made the scene-by-scene choices to depict racism, though.
