This is kind of idiotic, honestly. Most videogame characters, male and female, aren't very deep, thus falling into the realm of stereotypes. Not every game should be written like high level literature.
Basically, what this article is saying that is women shouldn't be in videogames unless they conform to a very, very narrow preconception. That's pretty absurd, not to mention self-centered, since male characters fill these secondary roles all the time.
The more intelligent solution would be to simply ask for more diverse female roles in videogames, not to eliminate stereotypes for females only.
