^Even if that's true, and I'm not at all convinced it is, it remains a vicious cycle. Superhero media will never attract more female fans until they stop consciously excluding and alienating them. I've read a number of essays and blog posts online by female comics fans who love superheroes in principle, who want to support and participate in the genre, but who feel excluded by the pervasive attitudes of the industry, the insistence on reducing female characters to oversexualized caricatures and women in refrigerators, the reluctance to give female-led titles an equal chance. There are quite a lot of female writers and artists in the industry now -- yes, including on superhero comics -- but there's still an uphill battle.
So defending the problem is just perpetuating the problem. If enough people stand up and say "This is not acceptable," then it can change. So I'm not interested in listening to your rationalizations and excuses for a practice that is simply wrong. And you shouldn't be either. You should be standing up and insisting on a change. We all should.
You're making a social argument and I'm talking business. Warner Brothers will support cultivating female characters as it does via DC comics, but its less willing to risk millions on a video production that history has shown makes less money than a similar concept for a male character.
I suspect that the real test of all of this is to see what happens if Marvel makes a Black Widow film. It will be interesting to see how well that does compared to Captain America: TWS, Iron Man 3 etc.
Given that WB is pushing for a JL movie, that might also serve as a catalyst for the ressurection of a WW film. But again, those female led superhero films will have to perform at levels equal to their male counterparts. If they don't expect the same blackout to happen all over again.
