Um. Huge femslasher here. The lack of it has never been from people being afraid. Most women in fandom are straight, they don't care about, read, or write f/f ships. That's it. I've written kinky stormpilot and femslash and guess what? Neither got any hate. Calm down and stop believing the hype that fandom is out to attack you. 98% of the time the rest of fandom doesn't even know you exist.
