And thus you've illustrated the biggest problem with you holier-than-thou progressive types. You think diversity is about numbers. It's not. One character like Black Panther getting his own movie or Luke Cage getting his own series - characters who started out as Black - does more for the cause of diversity than any ten characters you might switch from white to non-white on some crusade excused by [symphony music] ACTING! And there are more than enough non-white characters in comics to make that kind of statement.
In fact, if diversity were really a priority at Marvel Comics, they would be doing this version of Captain Marvel:
With Monica Rambeau, they would have a black woman playing a signature character and avoid having a character with an origin similar to Green Lantern, which the creators claim is some kind of problem. They would also be the first studio ever to feature a black female superhero in her own film. Yay real progress!
But they're not doing Monica Rambeau...they're just using Carol Danvers so they could cast White Girl Flavor of the Month Brie Larson, because a movie studio's ultimate priority is profit, not diversity. Their adding switched race or gender minor characters doesn't prove otherwise.
So, you're incapable of keeping two concepts in your head at the same time? That's okay. That comes with age and practice.
It is not a zero-sum game. I know what I want to see in comic book movies. I also know the only way I can guarantee I'll see it is to make the movies myself, which I'm not in a position to do, so I take what I can get. This doesn't mean I have to stop wanting to see what I want, or stop calling for what I want. It only means that I have to accept I won't always get it, and embrace it when I actually do.
