Chauvinism in Comics Fandom

While there are an ever-increasing amount of female readers/fans in the world of comics and superheroes, there also seems to be a never-ending supply of chauvinist fans who respond to titles such as Ms. Marvel or Batgirl with hostility, often using such charming phrases as "what is this feminist bullshit?" to describe their feelings. In a medium already hyper masculinized what does this behaviour suggest about comics fandom and its audience?
Maybe also mention attitude toward female cosplayers, creators, and characters.
