Who cares? McWhorter was making nascent right of center noises back in the day. Then he let loose with a bunch of black victimhood pailful shortly after that.
No use for him. At all.
We need to separate out the insights the person brings from the person themselves.
I can’t stand Nikki Minaj’s “music”, but her latest overtures rightward i do like.
Now as to McWhorter - his insights into linguistics are really very good.
