Definitely you are not responsible for bad fic and bad fic in a particular trope or field should not deter you from writing in that trope or field - quite the contrary! Like, I am aware that there's some pretty darn problematic Green Hornet fic (as well as some totally to-die-for awesome fic), but that just makes me want to write in the fandom more, to provide balance. Besides, it's not like there isn't femslash with canonically female characters out there that is misogynistic! You can only watch your own writing, not everybody else's.

So yes, to end on a joyful note, I love female characters playing central roles that are almost always left to men in pop fiction. Let me list some: Captain Amelia in Treasure Planet (spaceship captain!), Modesty Blaise in the comics of the same name (ex-crime boss, now independent contractor to Great Britain), Hildy Johnson in His Girl Friday (workaholic reporter trying to quit), the angels from Charlie's Angels (the movies, I never watched the show - brilliant private eye superheroes), Chel from Road to El Dorado (trickster), Parker from Leverage (burglar; though my favourite character from that show will always be Hardison, Parker and Sophie come directly after), Kaylee Frye (mechanic), Zoe Washburn (taciturn soldier), Xena (warlord/hero), the Romulan commander (ST:TOS), Ruffnut and Astrid from HTTYD (thugs), etc...
