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.
The right is way more hooked into the culture war, but plenty of leftist communities cannibalize each other via “no true Scots”-ing each other with intersectionality. I see very little patience or compassionate education on intersectionality, and instead see a competition about how quickly one can scold. Regardless of whether that’s valid, it sure as hell makes it difficult to build bonds with other groups or onboard new folks to leftist ideas.
