Compensatory narcissism is by far the most common type of NPD (see ScienceDaily and Kowalchyk, Palmieri, et al below, which fully supports my direct experience with NPD and AsPD pts for almost two decades). So much so that it seems normal to many (most) people in any authoritarian, dominance-and-submission-oriented sub-cult-ure.
And to anyone familiar with the developmental histories of as many of them as I have become since 2005, it's way obvious to me that CNPD is a collection of defense mechanisms that can become conditioned, instructed, socialized and normalized into the brain's default mode network to attempt to deal with having been raised by an NPD parent (or principal caretaker) who
a) physically neglects,
b) emotionally abandons, and/or
c) invalidates the reality of a child,
d) usually in the first five years of life, and
e) models the pseudo-self-empowerments of "righteous rectitude."
Otto Kernberg discussed all this in his seminal book, Borderline Conditions and Pathological Narcissism all the way back in 1975.
I have seen it in females, as well as males. Though females tend to display CNPD in a polarized "borderline organization" (a.k.a. "splitting," see not-moses's reply to the OP on this Reddit thread) along with stress-induced decompensation to temporary Learned Helplessness & Victim Identity far more often and noticeably than males with CNPD. Females with CNPD can be expected to flip back and forth from assertive "fight" to "flight," "freeze" or (very occasionally) submissive "fawn." Most males with CNPD tend to "fight" (intimidation is waaaay typical), moving only to very covert "flight" if they cannot win (be dominant).
Most males and some females with CNPD tend toward being -- not are far from always -- physically large, pushy and noisy, btw. Bullying -- verbal as well as physical -- is very common in this PD. Rage IS a Stage... that marks the narcissistic frustration of the "terrible twos," and the person with CNPD seems stuck in it. They are almost always, however, "right about everything" and sure that everyone would understand that if they would just "shut up" and listen to them. Which is almost always exactly what one or both of their parents did NOT do, making them frightened, frustrated, insecure, rageful and in dire need of some way to suppress, repress or even dissociate the symptoms of their complex post-traumatic stress disorder however they can.
Hurt people hurt other people.
A suggestion vis confirming your suspicion: If you run into someone who acts that way, gently find out what their parents were like. In my experience, one or both parents were the same way, though one may have been a doormat the current CNPD person wants no part of being.
