I've been looking for more clues that confirms the notion I support: That since Emotion is something you feel via Physical Sensations, and since Psychopaths seem to lack specifically in areas of Emotion that Neurologically are closely linked to parts of the limbic system that have to do with Empathy, Fear, etc., but also with Sexuality (and to a large degree with gender - which may in fact be the reason there're three times more Male than Female psychopaths), it may also be a prevalent trait with us that we aren't quite as strictly Defined in our Sexuality as are normal people.
This picture was listed as Androgynous - but whatever the Gender of this person, it's Red Hot Sexy!
It's been harder than expected to find anything on the gender and sex issue than I had anticipated, and the little I found - articles, primarily, and excerpts - I had to pay hard cash to read.
When reading the book 'Snakes in Suits' by Paul Babiak and Robert D. Hare, I came across the following citation in a chapter about how we Psychopaths manipulate people, that describes very well a much used tactic among Psychopaths - be they Female or Male
Everybody concealed that little hell in himself, while publicly pretending it didn't exist--and when he was caught up in it he was completely helpless. Cathy learned that by manipulation and use of this one part of people she could gain and keep power over nearly everyone. It was at once a weapon and a threat. It was irresistible. And since the blind helplessness seems never to have fallen on Cathy, it is probable that she had very little of the impulse herself and indeed felt a contempt for those who did. And when you think of it in one way, she was right.
Most Psychopaths I have met or heard of - myself included - do what Steinbeck describes. We do things according to gender first of all, but we're also individuals and have preferences and character traits which may influence how each of us actualize the fundamental idea, but mostly it is all a variation over a Stereotypical theme. And that is most likely the reason why we come across as such explicit representatives of our gender.
But that above passage which Babiak and Hare cites in 'Snakes in Suits' is pretty telling in my eyes.
Male psychopaths pretty much do exactly the same thing as we see John Steinbeck describing with the woman Cathy. Both gender tends to represent the gender they were born with because it is easier, and most people respond to that, rather than the sexuality of minorities.
On another note in this regard: I have noticed, that once we shed what has been called our 'Mask', the gender differences become less obvious. In fact, I know of more than one Psychopath who on the Internet present themselves as a gender they do not represent in so called 'Real Life'.
