Nobody attacks things like Manga or Twilight, or High School Musical, or Sex in the City for appealing primarily to women and girls. Nobody goes in and tries to change those things to appeal to men. Nobody is pushing to make Twilight more like Blade. But constantly I hear how comics need to change to be more girl friendly. Super heroes appeal primarily to males. I make no apologies for that. I make no apologies for a genre that has given us Watchmen, Kingdom Come, Mark Waid's Empire, Ultimates, The Dark Knight Returns. Some entertainment is gender inclusive some forms arent. Its great when some of the superhero stuff appeals to women. But the core of the fan base will always be male and I for one don't think there is anything wrong with that. I don't want to see Marvel forget who they're selling to and end up churning out more "gender inclusive' crap like Arana. Go too far down the road of trying to expand the appeal and you will lose your original fanbase
I assume you're not familiar with the concept of " privilege " as it relates to identity politics, since you seem to equate the fact that girl's media isn't pushed to be more like boys with the opposite ( despite the fact that being a male gives you more opportunities in terms of entertainment as well as wealth and success, and has for the entirety of human civilization ). As much as you might not like Arana ( and you didn't have to read it if you didn't want to, so it's hardly like Marvel took away your comics by publishing it ), the gesture does little to switch the situation so that males are the disenfranchised audience.
Also, Watchmen, Kingdom Come, DKR, Ultimates et al are the examples of works of art that can appeal to multiple audiences because they're so good they transcend such demographic notions. The middle ground superhero comics are still a boys' club by and large, and if the " original fanbase " wants them to stay that way without any gestures to other groups, they should be jettisonned.
