That's the R2 way of phrasing R{1,2}, like "race traitor" is the R3 way of phrasing R1 or celandine's phrasings are from an R1 perspective. (Not saying you are a jerk; just trying to separate out precisely such connotative differences from these useful clusters/concentric rings in peoplespace.)

Possibly, I couldn't quite figure out Mixed Nuts' definitions because he seemed to be implicitly assuming that accurate priors were equal over races.

(N.B. that if this definition wasn't question-begging and/or indexical it would imply that iff accurate priors are equal over races then the genuinely colorblind are racists.)

Well they aren't. Nevertheless, I should probably have said something more like:

A "Racist0" is someone who rationally believes that priors aren't equal over races.
