Or perhaps he just genuinely likes the characters he chose for the team and thinks they will have interesting dynamics, regardless of their race.
How you are reading it, feeling about it, internalising it...most likely isn't the way Duggan is writing/intending it to be read. He's not writing for you and us PoC specifically. So why take it so personally?
Did Claremont suddenly decide that Storm was too powerful a Black character so he depowered her...for years?
Fictional writers putting "limits" on the PoC characters they're writing does not in any way devalue and limit us living, breathing, beauty-full, resplendent Persons of Colour, IRL. I do not feel any less of myself, of you, of all the PoC comic book fans and in general because one writer does something that I don't personally agree with. That is insane.
