Historian of civil rights movement here. The idea that the fate of poor/working class white and black people are linked and integral to any durable movement toward economic and racial justice is a core idea of the black freedom movement, and the black radical tradition broadly.

By standards of todays progressive "anti-racist" concern trolls, Hubert Harrison, Phillip Randolph, MLK, Bayard Rustin, Semptima Clarke, Ella Baker, list goes on - would have been found wanting, insufficiently woke, (clutches pearls), for "tolerating" racism, which they did not.

Condaleeza Rice enlisted the civil rights movement in service of Iraq War "democracy promotion," Obama made it about himself, HRC used it to argue against breaking up big banks, now Bernie was somehow sympathetic to segregationists. A thoroughly degraded discourse: don't buy it.
