It's the same as Tony Stark's sexism harming the likability of his character, early on.
Equality:
Tony Stark's sexism hurt his character.
Carol Danvers' "girl power" hurts her character.
Luckily, though, Iron Man wasn't chock-full of sexism.
Captain Marvel was a mediocre movie, only in-part, because of the feminist elitism. The movie suffers from far more problems than the singular argument you're trying to make. You've simply focused on 1 thing that you think you can argue. I suppose that means you're conceding all of the other concerns. A "7/10" is mediocre.
