It is not so much disgusting as it is annoying. Women of Color, aside from the occasional Asian female actress, are difficult to find in science fiction and fantasy adventures as even likable background characters.
This is incredible,
"aside from the occasional Asian female actress" because they, as a group, don't fit nicely into this theory, Asian actresses just don't count? Grace Parks had a prominent science fiction role in nuBSG as Boomer. Linda Parks's role as Hoshi was hardly a token minority background character, she was featured in a number of episodes, she became Empress of the Empire!
Does Infinite Diversity mean that People of Color can't be competent Do-Gooders?
