I just watched this video on Female narcissists and was wondering what your thoughts on this subject are.
This guy's basic premise is that we shouldn't view NPD, BPD and HPD as sperate diagnoses, it's just that BPD and HPD tend to be female manifestations of narcissism where classical NPD tends to be a male manifestation.
He goes into detail how the personalities all share common characteristics of being manipulative and having a fragile ego that needs special attention.
The video is a bit long winded so if you don't want to watch the whole thing that's understandable. You can get the jist of it in the first 15 minutes.
