Borderline Personality Disorder manifests in different ways according to sex and gender. Borderline women turn a lot of their rage inwards into pain in the feminine style, while Borderline men turn their pain outwards into rage in the masculine style.
In both cases what is being internalized or externalized is something I would call different things: Pain, hurt, negativity. Possibly pain fits best. So in that sense all outward rage is simply inner pain directed outwards. And all inner pain is simply outward rage directed inwards.
Also a very high percentage of Borderline men are gay or bisexual. This makes sense as BPD is a female or feminine disorder. Borderline is simply the way that the Feminine Spirit goes crazy, and in that sense, all women are a bit Borderline.
Females go crazy in histrionic, borderline (both dramatic), and depressive (inwards) ways.
Males go crazy in psychopathic, narcissistic (male styles of dramatic, which are often quite aggressive), and manic (outwards and not uncommonly aggressive) ways.
- Narcissism in the male or masculine person = Borderline in the female/gay man or feminine person.
- Psychopathy in the male or masculine person = Histrionic in the female/gay man or feminine person.
- Mania in the male or masculine person = Depression in the female or feminine person.
I have argued before that male and female psychopaths or criminals are different, hence, we have masculine and feminine criminal styles:
- Generalized criminality with a lot of aggression and even violence in the male = Prostitution and thievery in the female.
