Great and important essay. The high opportunity cost of this movement really resonates with (and scares) me.
And I suspect that the pervasive moral grandstanding I associate w/the misapplication of the term 'racist' really does both dilute its value and inspire targets to go find association elsewhere. Often, that elsewhere is a really unproductive place and creates a 'versus' where we could be seeing more collaboration and cultural cross cultivation. But that may be the point for some antiracists, which is even more disturbing!
