Who, BTW, is Black, but who writes an opines principally as a very intelligent, well educated, common sense person. From all his writings I see a man who certainly has a Black identity, but not just that, he has a Black American identity. As I believe the majority of Blacks do. However there certainly are American Blacks for whom their Black identity is primary and very strong, and we hear from them constantly now, with things like the 1619 Project and demands for reparations. Which I find very divisive and unfortunate for us all.
McWhorter is against the "soft racism" of giving Blacks preferential treatment in various ways. In essence, he's saying the time for Affirmative Action both formally and informally to come to an end. This doesn't make him popular with the Left and of course the more aggressive Black activists. He deserves credit for his commitment to truth and his willingness to put himself on the line for it. We are short of Americans in responsible positions with such courage.
