This is a ridiculous subject. These are not real races, thus cannot be subject to the label "minority group". There is no ethics, no rights, nor any reason to even consider equality or representation of fictive/imaginative "races". It's like people invent issues for the sake and of complaining.
Fact is, this is a digital interpretation of a ruleset. At best you are trying to argue equality of bits and bytes represented by pixels.
If people actually identify on a deep personal level with the character, to such an extent it's a problem with out certain demographic representation, then the people in said group probably shouldn't be playing the game in the first place.
