Props to the Vox author for responding carefully and comprehensively to accusations of misrepresentation. I do wonder if it will make a difference, though, as the audience this piece is talking to and the audience Wax is addressing probably do not in any way overlap.
Taking a step back, this seems to me like an inevitable response to the inevitable decline of the white majority. Losing their majority, those who most valued holding it seem to be going through the stages of grief. This appears to be the transition from anger to bargaining. (But maybe that's a generalization too broad to really capture what's happening.)
