The diversion is the idea of rainbow capitalism. For example: fighting for the right for people of any identity to own slaves is not a valid goal and also won’t “free the slaves.” Ending slavery is the goal. Rainbow capitalism acts as a shell game to divert energy toward token concessions and labels them victories. Anti-racism and feminism should be (and I would say, are) at the core of any coherent flavor of leftism, but diverse oppression is still oppression and a rainbow flag on a Raytheon missile is not a win.
Edit: should have read the comment further down. Said what I meant but with gooder words.
