I've known so many women who say they don't get along with other women due to drama that I wonder why they don't meet up with each other and become friends!
Conversely, my best guy friend has pretty much no male friends, but lots of female friends. Also, some of the most drama-causing people I know are guys, so I honestly don't know where that stereotype even comes from. I remember a friend telling me about some of her male coworkers who were going on about women being such gossips--then about half an hour later were gossipping themselves, just as badly! Apparently when *they* do it it's not gossip, just sharing information, or something.
I am really happy that we are getting more nuanced portrayals of female characters in fiction. It seems like for awhile there was such a backlash against the stereotypical damsel in distress character that women who conformed to gendered expectations of the time (specifically thinking of historical/fantasy novels here) weren't really considered good protagonists.
Though there are certain fans who are just *really* harsh on female characters in general; I've noticed this in some of my fandoms. (Game of Thrones, I'm looking at you...) Male character kills someone? He's awesome and misunderstood! Female character says something mean? She's the worst and deserves to die!
