That still doesn't change the fact that those are still stereotypes. Nobody asks for an Asian lead until said character has some connection to Asian culture. That's what always happens with these things. Why didn't anyone clamor for an Asian Iron Man, or Daredevil, or Jessica Jones, or Hulk (since we have one now in the comics), or countless other superheroes in film who are white? Because as much as people want to make themselves feel better about caring for Asian representation, they are just pretending. You can't fix a stereotype with another stereotype.
