If racism is to be abolished then why are you so offended that we want representation? And what created that need for it? Could it be racism that dictated who would and wouldn't be represented?
Viewing post in POC tag?
Can you specify how sufficient representation would look like? Because I know that term from slogans like no taxation without representation. And games and fiction as a whole is not a thing that warrants any kind of representation in the first place.
You can even make stories about talking animals. Who was represented in those? Whom did Pac-Man represent?
One makes a thing and people like it, or not. What good would it do, to be "represented" in games that no one plays? The most popular games are games where you can customize your character anyways, so the whole concept has a very slim application anyways.
