This whole issue is probably the reason they didn't let Ava Duvernary direct. I still think she was fully prepared to pull all types of these social agendas in this movie and Marvel wasn't having it.
Lowkey, I got this vibe too. Or rather, her vision wasn't aligned with what Marvel had in mind and she didn't care for the restrictions i feel. Mind you, Priest, Hudlin and Coates are all "pro black" but it's not a homogeneous concept, as we saw in how they each prioritized their runs, especially when it came to the depiction of Wakandan men and women. And of T'Challa.
Coogler and Ava are both pro-black too I imagine, but ultimately Coogler is a "bro" who, like with any black male who has even a modicum of physicality/masculinity to them, can embrace the childhood importance of simply having a black male superhero, before any of the other social justice or political stuff that will still be there in some form.
Not saying a woman couldn't do it or that a white person couldn't or a gay person, and someone like Coates is more feminine than masculine anyway as far as i'm concerned, but Coogler just seems like the perfect fit. And i'm confident he'll prove me right on that
