A few months ago I pulled out my phone to show my coworkers son my phone background, a picture of Sam Wilson as Captain America. He looked to the phone, then to me, then back down to the phone. After about a minute he looks at his mom and in the most excitable voice ever says "MOM MOM LOOK. I can finally be Captain America for halloween!!".
^That's why representation is important. I hate this argument of "just make new characters". It does two things. First, it ignores the impossibility of creating new icons. Fact is no new character is going to achieve the name recognition that a Superman, Batman, Wonderwoman, Captain America, Iron Man or Spider-Man will have. Second it reinforces the idea that these characters aren't for everyone. "Yes asians you may enjoy our Spider-Man but please leave him as white as you found him please and thanks". Sorry, that doesn't work for me. Yes, I support Luke Cage and Black Marvel and other diverse original characters, but there's something about looking towards CAPTAIN AMERICA, an icon both in and out the MU, and seeing yourself reflected in him that just isn't going to happen with another character.
