Six,
While I am easily able to admit I don't know the teacher's motivation (and have done so at least once on this thread) I am at a loss to understand when it would be NEEDED to make a statement like the one that was made. "A little Sambo sitting in the back of the class"? Why could she not have said, " a child sitting in the back of the class"? And, personally, I think the fact that she added "little" to the term goes far more towards showing some sort of bias than otherwise. There is possibly some reason she needed to identify the child by race, but then you have to accept that she knew the term referred to blacks, and it makes more sense to believe if she knew the term referred to blacks, then she knew it wasn't nice, at the very least.
The fact that something isn't used often in no way detracts from it's offensiveness. Because I don't use slurs personally, I won't go into the many words that used to be popular, are no longer often used, but still have the same intent and affect as they did decades ago. I know you won't like this, but I can't think of any other way to say it: calling a slur mild shows that you likely don't know how it feels to be called one. I am not saying that you have gone through life without issues, problems, name calling,etc. I am saying most every minority person I know reacts to slurs, old or new, and that's just the way it is. (and by react, I simply mean they are offended)
The one thing I agree with you on is the story is sparse on details. Maybe it wasn't a big enough story to warrant a follow up, but I could not find it anywhere. What it does say, however, is that two attendees of the conference reported the incident. Two. Not a lot (although I admittedly don't know the number of attendees). Seems like she almost did get away with it.
I just re-read the article again, trying desperately not to be biased, and there is no way I think this was said without racial bias. You can sugarcoat it by calling it "home spun wit" but it's a slur, and she should have had more severe a punishment than paid leave.
Just my opinion, and I think you and I will likely have to agree to disagree on this one.
