I’m not sure 100% who is speaking here, David Gordon, Anthony Flood, or C.L.R. James, but:
The Stalinists, James claimed, viewed blacks as subordinate shock troops of a prospective revolution rather than independent actors, and this Stalinist line Aptheker faithfully followed.
The Dems view blacks exactly this way, too.
For example, the crimes that blacks, damaged and weaponized by the welfare state and drug war, commit are just one more way of shocking the bourgeoisie.
