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.
