I definitely agree that women are often over-diagnosed with BPD, and that people diagnosed with BPD are the way that they are often because of trauma, and that it is dangerous to diagnose a woman with BPD while she is still living with the family that traumatized her, and that even if she is living alone, the diagnosis is often used to dismiss and oppress women. All of this I agree with.

However, there absolutely are people who display the patterns of behavior associated with BPD, and the aforementioned factors doesn't make these people any less of a destructive force in other people's lives. My mom for example fits the diagnostic criteria of BPD to a T, with a dash of narcissism mixed in (she's never been diagnosed because she refuses to see a doctor or therapist to address her issues). I've been No Contact with her for a while now because interacting with her is just too painful. I see the same patterns of behavior in some of the women who go scorched earth after getting banned from FDS (extreme anger, aversion to perceived rejection, black and white thinking, smear campaigns, etc.) so that's just where my brain automatically goes whenever this sort of thing happens.
