Better yet, read them! They answer your question.
>The existence of two books endorsing a point of view is not evidence that this point of view is mainstream.
Since "mainstream" is a judgement call, I don't think anyone can directly demonstrate that to your liking. If you're genuinely curious about this subject, this would be a good time to do some reading.

What question is that? I don't see how reading these books could possibly persuade me of anything other than there are two people who espouse some overly extreme ideas with regards to racism. And I will happily concede that without reading them. So I was wrong when I said that "absolutely no one" believes this crap. Two people believe it. Maybe even 100. Maybe even 1000.
But McWhorter claims that third-wave anti-racism is mainstream (his word) and so far I have seen zero evidence of that.
Between The World and Me spent over 100 weeks in the NYT bestseller list. Ibram X. Kendi, author of the other book cited, wrote another book, How To Be An Antiracist, which was a bestselling book in the U.S. 2020. Another bestselling book in this vein was White Fragility.
