I mean, there’s support and then there’s enabling. Not all things that ND people do are good, either for them or those around them. We as a community don’t act like it’s ok for Autistic people to go around grabbing women’s tits “cause they don’t understand social conventions” (though I’ve absolutely come across this argument before, which infuriated me), why would we act like it’s ok for NPD people to manipulate and emotionally abuse those around them “cause it’s just the way they are”? The goal is to support them in a way that limits harm: both the harm that comes to them from outside, and the harm they can do to others.
