I see nothing racist in Black Panther, and I see no racial hostility in the movie. As for the scene you talked about, you have to take note of the temperament of that particular character, that dude is an angry, hot tempered person and vindictive person and it reflected in all the roles he played, not only to the white woman. There is absolutely no white shaming in the movie, it reflects in the way the white man was treated using technology and how he also helped them in the fight.
Hi Oluwa, whether the personality of the character is tempered or not, that kind of speech shows a racial attack against the woman. This is not the only scene where it occurs. When the US ambassador wakes up in Wakanda, the princess, also tempered, call him "colonizer."
And there are others more subtle, where all the representatives of the world look at Wakanda´s king over the shoulder phrasing that he is the king of a third-world country displaying arrogance towards the nation and few others.
An in-depth analysis of the racial hostility could be made, however, my point, or what bothers me, it is not the depiction of the situation but how double standardized is the society since if the situation would have been the other way around, the film will be surely banned.
