> What I mean by race relations is directly related to how the teacher did not know why it is not OK for her, as a white women, to use a particular word.

No, I think she understood perfectly well the usual taboo. And snapped and used the forbidden word anyway.

And then used the episode as a teaching moment, maybe the only time (in the article) when she had the students' attention. And managed to point out to the students how thin their logic around this taboo actually is.

Is this the only way in which you think her uninformed? Your comments seem to come back to this one point repeatedly, which sounds like it occupied 15 minutes of a decade's experience.
