From the New York Times:
Where Did All the Black Teachers Go?
By BRENT STAPLES APRIL 20, 2017
… States and localities with significant black populations are beginning to recognize the whiteness of the teacher corps as an obstacle to student achievement. At the same time, statistics show that districts are doing a miserable job of retaining teachers of color and that more leave the field each year than enter it. A 2016 report by the Education Trust shows why. Among other things, African-Americans interested in teaching black students find they are steered into positions where they teach only black students. The same teachers complain of being pigeonholed as disciplinarians, their other talents rendered invisible.
In the NYT, use of the word “whiteness” correlates highly with anti-white attitudes and anti-white initiatives. The word “whiteness” in the NYT is more or less intended as a racial slur.
