Ugh I fucking hate the 'why isn't this ethinicity in the canon?!?' argument. Leave affirmative action out of the roster and let creators create as they see it. Nothing is worst for canon or MORE racist than wedging another race in out of obligation, despite the original intent of the canon.
There's always one group that gets pissy because you can't include them all and when you do it completely implodes on itself. Where the hell are the tranny eskimos i say?!? Why don't I have a black canadian mountie character?!? Where's the Muslim Puerto Ricans at?!? CAS mode...they're in there!
