No, this isn't true at all. I believe in anti-racism. I'm very largely against Antiracism (I hope I'm getting your framing right thereš ).
I agree with you , these "thought-leaders" who are claiming that racism is lurking in every interactino are doing great harm to genuine anti-racist efforts. And the lunacy we're seeing is the inevitable result of their stupidity. But what you seem to be missing is that they don't speak for the vast majority of people, black, white and otherwise.
Most people going along with them are doing so out of pure self-interest rather than because they want to end racial inequality. So yes, while what I speak about in the piece is the logical conclusion of the ideologues (or actually, the logical conclusion is much worse), that's exactly why we should be worrying about it.
