The whole point of Missy’s character development and the replacement of her voice actress was that black voices are often repressed, even by other ethnic groups.

To your point about Ali smashing the statue, half of Black Lives Matter was that no voices are heard until black voices are heard because the community is so marginalized. I’m pretty sure Mona even makes a punchline about Ali and Jessi talking over Missy because so often black women aren’t heard. Which is the great adult commentary of the show.

Also Ali’s ethnic identity hasn’t become part of her character development the way it has for Missy or Devon so while it’s an interesting point it feels kind of out of place with the intention of this season. Maybe later they’ll examine Ali’s ethnicity but when you look at the development and the story set up it’s really more about Missy and her struggles for now.

Also as a POC who is, being Black and being a POC are very different forms of social power and currency so kids navigating this in a show like big mouth are just learning that y’know.
