The English word “narcissistic” existed long before the diagnosis, just like “Sisyphean” exists without an attached disorder (ODD in another timeliness, maybe).
I find your claim dubious, but in any case, the N word existed in english before it became a slur too. But centuries of racial abuse made it into a slur
Why do you think the N word existed in English as anything but a slur? Narcissism and narcissistic personality disorder are not equal. I’m open to changing terminology if it’s doing harm, but I think this one needs to be that the term for NPD should likely change. From what I know (and correct me if I’m wrong please), the common usage of “narcissism” has very little to do with NPD, which was coined later and seems almost derogatory in itself (in effect, grouping those with NPD along with the type of asshole commonly called narcissists)
Edit: I have been convinced that this story I was told was wrong about NPD. There doesn’t seem to be a usage of narcissism outside of attempted psychological prescription before 1900 in english, and only first in 1899 in German which caused its use in English.
The common use of narcissism in the vernacular originates with Christopher Lasch’s book The Culture Of Narcissism, which put forward the thesis that NPD was becoming more normalised in contemporary america. That book inspired self help guru hacks to sell books which told people that all their problems are caused by people with NPD holding them back and abusing them. People love being told that all their problems are caused by a vulnerable minority that seeks to destroy them, that’s how Hitler got into power. So anyway, these books inspired the idea that everyone’s abusive parents and bosses and partners are narcissists, and once that happened, more and more people started drawing on this growing linguistic awareness of the word narcissist, generally falling into one of two camps: Either they hate people with NPD and think we’re all abusive, or they don’t know the history of the word and just repeat it without thinking. And those two groups sound identical when they throw the word about as an insult. When I call out use of the slur, I never know which of the two groups I’m about to have an argument with. Sometimes it’s both.
