I do hope you aren't suggesting pointless and ongoing conflict in nerddom is a new phenomena, brought about as a consequence of our newfound "cool kid" status?
These issues are obviously much bigger than our fandom, or sci fi in general, they are permeating every aspect of society, including those which have no desire to be permeated. But those are the time we live in, we can't choose that, all we can do is act according to our own principles and try to make that matter in whatever walk of life we choose.
I'm personally not convinced "girls in sci fi" is remotely a new thing, nor am I convinced the old trope of the socially inept nerd really held up under scrutiny. Personally I've always been a confident chap and have spent a lot of time around female roleplayers and comic book fans.
Rather the scrutiny did not exist or was disjointed and isolated,lacking any coherency and leaving the stereotype with free reign in the media. The internet has changed that much at least and a great deal of the backlash has been about the industry acknowledging at long last what was there all along, a much more diverse and dynamic fan base than was previously suspected.
In that model why shouldn't the people who were sidelined for so long want to finally be recognised?
