It sounds as if you are saying there is no chance that much of anyone who is white can be antiracist, or at least that's what my reading of the article is.

Yes, white people are massively racist, but if you argue that, because of the massive racism we've displayed in the past, there is no chance of working-class whites breaking with racism- and the creation of an antiracist future will require that sort of break- what hope exists, then?

And yes, Fox News didn't always exist, but there has always been a massive propaganda effort to persuade white people, especially working-class whites, that they should vote against their economic interests in the name of a mythical "superiority" that matters more than any actual possibility of change, any end to their hardship- and the post-Reconstruction period involved a massive effort on the part of the Bourbon elites in the South (and industrial ruling-class types in the North) to divide working-class people by race. If working-class racism was always inevitable, why would that have been done?

What hope exists if you work from the assumption that working-class whites are unchangeable?

Why not challenge, instead, the Democratic Party's insistence, for most of the past forty years, on being completely pro-corporate and anti-worker on economic policy, challenge their refusal to speak about mobilizing people who have little or nothing because the donors don't want that?

If's not as if a message that incorporates social justice AND economic justice, adjusted to account for intersectionality, can't be at least part of the way forward, and it's not as if any message that links those justice struggles has to leave Black people out in the cold.
