Google Dr. Robin Diangelo? She puts it best. You'll likely disagree with everything she has to say because you want to. However, I challenge you to at least listen to her. After that look for some more research into implicit bias. You'll find everything from Xbox Kinect experiments that show how the body language of White teachers can change (for the worse) when talking to minority students and more things that will change your perspective. That is if you want your perspective to align with the truth. I am guessing that you are most comfortable with your existing point-of-view.
> You are of course wrong. And I must suspect the reason you are wrong is that you are trying to mine the situation for a racial angle.
In the USA you don't have to mine. Race plays into many (if not all) situations in the country whether you want to believe it or not. This one most definitely does. The article explicitly uses certain words. Race is right there in the article my friend.
> That's exactly the problem I describe above...
I would have to agree with that statement. But I don't see this teacher as one who has the proper education and empathy to help. If she really, truly, wants to help she can first further educate herself in race relations and the mentality of the disenfranchised.
