I would rather we focus terms of the abused. And also, differentiate between narc abuse between siblings, between adults and between a child and caregiver / parent. I do not in any way mean to negate anyone else’s experience, but it is different to experience the abuse as a totally powerless and dependent child than as an otherwise autonomous adult with self-agency.
Maybe it wasn’t pre-1950s or in areas where women tend to not drive, read or have jobs and careers.
At any rate, I’d rather focus on the victims of the abuse, not the abuser. That said, I do realize that we have to ‘characterize’ the abuser in some manner. I tend to appreciate the simple perhaps archaic old-school phrase “Morally insane.” Sure, morals vary, but most people can agree over the millennia that taking pleasure from being the cause of another’s non-consensual pain, loss of self, job, reputation or life is morally wrong. There’s something ‘wrong’ with people who do that.
My abuse happened in the 70s and 80s where beating your child was accepted, and acting defiant / hateful towards one parent was considered ‘normal teen angst.’ My children were not nearly as defiant as I was. I was that way because I was forced into and out of relationships, forced to take on beliefs that I didn’t want, forced to act in ways against my own integrity and forced to take blame for being forced into doing those things.

I again mean to not negate physical sexual assault; it’s real, it hurts and it can change your neural networks permanently. I know that for a fact.
I characterize my mother’s treatment of me as “Life rape.” Because someone forced their will on me and forced me to live in a way that I had to adapt in order to stay alive and somewhat sane. That’s effectively what rape is.
I made decisions well into my adulthood for the sake of getting her to stop nagging me / trying to control me. I married complete scumbags, because it made her happy (to see me miserable and being abused by proxies). Plus, she had the hots for one of them, calling him her ‘soul mate’ in front of me.

I tend to like things simple and blunt. Such as “Child of an abuser.” “Partner of an abuser.” “Sibling of an abuser.” We do tend to be the ‘identified’ patient and the one most likely to see psychological intervention for own issues.

There is a belief that you can be abused by a narcissists as an adult even if you were never abused as a child…but I contend that there had to have been ‘something’ that happened that made you vulnerable to them, blind to their evils.
Something that made you accept the ratty pair of mittens they offered you on a cold winter day, the same old pair they offered to everyone else; you had no mittens and were freezing, so you saw value in them. While everyone else already had their own warm, fuzzy mittens and didn’t need the raggedy ones the narcissist had to offer.
We must ask ourselves, “Why didn’t I have any of my own mittens?”
