its literally just straight demonizing a disorder. its the exact same thing as stereotyping autism or BPD, its abliest and just rude. its not real and not every person with NPD is an abuser : coming from someone with NPD !!! it is not ( and never is ) the disorder! its the persons problem!! not all narcissists are abusers and not all abusers are narcissists. if someone blames their abuse on the disorder or in tandem blames their abuser for having their disorder they're not educated enough on the disorder and are pointing fingers at the wrong thing. people with BPD/NPD/ASPD etc etc CAN have good relationships. people with those diagnoses can and ARE good people.

as said before its not the disorder that makes the person evil, its the person themselves that chooses to go down that path.
hope this doesnt sound too rambled

the abuse that falls under narc abuse is real, but the term itself is god awful at describing them properly, and gives unnecessary ties that abusers are "narcissists". and the thing about doing that is people use it to dehumanize abusers, as if abusers aren't people too and that their actions can't be replicated by someone else who "isn't a narcissist". anyone can be an abuser, not because of a specific trait they have.

it also unfortunately makes more ties that people with diagnosed narcissism, or pwNPD, are inherently abusive. i've seen people go "oh, i don't think pwNPD are abusive, but the term is hel-" no!!! there are so many people that believe so and use the term because of so!! just because you don't believe it means that you automatically get a pass!

tl;dr not a helpful term and people should stop using it altogether.

The whole narc abuse shit is just literal ableism, not only is it generalizing, it also doesnt make sense. If you say you experienced narc abuse youre blaming the abuse on the disorder, NOT on the person who did it, theyll always be able to use their disorder as an excuse rather than taking accountability for being a shit person. You werent abused by the disorder, you were abused by a shit person who happened to have that disorder, yes narcissim may increase their shitty behaviour, but it would only affect the personality they already have, so they already need to be a shit person to begin with. Being a narc on its own wont make you abuse anyone, if youre an abuser and a narc, your abusive behaviour may be affected by your narcissism yes, BUT that doesnt mean EVERY narc is like that. You wouldnt say "autism abuse" simply bc the person that abused you is autistic.

Not to mention the so called narc abuse literally fall under any catagory of abuse that already exists, theres no need to make a new term simply bc the person happened to have that disorder or shows traits of it, itll either fall under emotional, physical,or sexual abuse, etc. its time we stop blaming disorders or traits, and blame the actual person for being fucking shitty
