End of disussion.
If you’re already ceding a descriptivist account of language, arguing that white isn’t a race is probably foreclosed.
that’s a good point, although if we’re talking about tactics internal consistency isn’t 100% necessary. more important that the rhetoric we choose resonates in the way we intend with the audience we’re engaging with
“whiteness is the absence of race” is an interesting way of framing it that the average person probably hasn’t thought about before. could then segue into the arbitrary nature of white/nonwhite and how it ties into power structures and class relations. ideally sidesteps defenses and encourages novel/critical thought
also could avoid internal consistency issues simply by wording it like “the way I like to look at it is…” rather than a strong assertion.
