No, I suspect the concept will never be abolished socially until the capitalism that sustains it and simultaneously uses it as a functional tool is destroyed or negated, but as the contradictions of capitalism develop further in conjunction with climate change, so does whiteness as a concept; maybe it expands, maybe it contracts, maybe gen alpha resurrects the Young Patriots Organization and bisects whiteness and transforms it into some pseudo-radical identity, who knows, of course I highly doubt that will never happen, because at the end of the day whiteness has no content beyond exclusionary hatred

But what will definitely happen is whiteness will change over time along with the contradictions of capitalism, and as that happens the artificiality of it becomes more apparent, and as materialists it's always a sound strategy to point out the artificial, to de-essentialize racial rhetoric and stress when something is not set in nature, despite ideological claims to the contrary

And I take your point about being "ideologically advanced" well, but ironically my usual approach is simple and fully in line with American socio-economic history; desegregation, but instead of arising out of segments of the black community like in the past and mediated reluctantly by a hostile state, it's an "internal position" advanced by white radicals as a social movement, hardly an ideologically advanced position

Of course, don't ask me the likelihood of something like that happening, because I can get real doomer about the United States
