That's interesting about the female characters--I hadn't thought of that. Whenever discussions about the female characters come up I think it sort of underlines the problem with any type of minority character in literature. The best thing about being a white male character is that nobody thinks twice about having you do anything at all. You can be a traitor or a villain or a hero without ever representing your entire gender or race.

But yes, it is good to show people crossing over from one side to the other. There's something in the DE mentality that appeals to the human mind and always has.
