She may not be an artist, but an art critic doesn't have to be. Rallying to silence her is simply put, a juvenile, knee-jerk reaction that, in a broader context, only serves to silence a feminist perspective. In this case, trying to shoot the messenger does more to legitimize her concerns about the industry as it demonstratively showcases how the Male Defense Force responds to the mere possibility of a fairer portrayal of the genders in this artistic medium.
Get over it. Just as there is sexism and misogyny in every other entertainment medium in spite of feminist movements, these things that you find dear to the realm of video games will survive and thrive even if Anita's influence magnifies a hundred fold. Just sit back, see what happens, and critique the final product. That's what secured her role as a consultant anyhow. The development team clearly listens to its critics, so Mirror's Edge 2 may be a learning experience for gamer and developer alike.
There's no sense in becoming hysterical at this stage.
