From Eli Dupree:
I discovered sociopathworld.com this morning, while investigating cultural stereotypes about female sociopaths. I think you and your readers might like to read this graphic short story that I wrote a few months ago.
I'm an agendered non-empath, among other things. (I'm not trying to reclaim the term "sociopath", so I don't use it for myself, but I think I'm what you would call a "sociopath".) People don't generally categorize me as female, either (they categorize me as male), so I'm not directly affected by any stereotypes about female sociopaths, but I'm really interested in both feminism and neurodiversity. I also have Asperger's (that's right, I'm an aspie AND a non-empath - I recognize that those are significantly different things, and I'm both of them.)
The biggest single stereotype about femaleness and sociopathy that I found on the Internet was "borderline personality disorder is the female equivalent of antisocial personality disorder". That's complete bullshit, obviously, but it kinda illustrates how people think about it - they expect female people to be more emotional and more empathetic than male people, so their model for "sociopathic man" is a cold, heartless person while their model for "sociopathic woman" is a "crazy", emotionally unstable person.
So, basically, mass culture doesn't even have the language to talk about actual female non-empaths, because the stereotype is that they don't exist. On the plus side, that means there's no particular stereotype threat for female non-empaths in particular. On the other hand, the way our culture coerces apparently-female people into displaying empathic behaviors probably hurts female non-empaths a lot. I don't think it's healthy for almost anybody to live with a false persona all the time. (There are probably people who are just as happy lying all the time as they would be if they were open to people, but just being a non-empath doesn't automatically make you like that, nor does any other specific neurological condition I know of.)
