I have been struggling with this because a lot of people around me use it in this manner when they do something dumb or they act in an awkward way and they’ll be like “oh, that was autistic of me” or “I’ve got the tism” and I always feel so uncomfortable but I also don’t know how to raise it or what to say. I am myself not diagnosed, but I’m pretty sure I am on the spectrum. I was just wondering what you think of it and how you handle it.
No, it comes from Narcisuss. The word predates NPD by almost a hundred years.
But even if it did come from NPD, it still an objectively negative trait worthy of admonishment. It’s not a slur to describe someone’s persistent selfishness as narcissistic. It’s the definition of the word.
[Edit] it’s as much as a slur as using “psychopath” to describe someone who kills squirrels for fun
