It can be dangerous to portray that narcissism=self love and can add to the stigma. NPD is a disorder that leaves people with a mutilated idea of self love and security. An inflated sense of self importance in NPD can be mistaken for self love by the person suffering from NPD, but they are not the same thing. Narcissism leaves you with a lack of empathy that damages relationships and can make you disregard the feelings of others in self defense. Self love gives you security that leaves you open to listening to your own feelings as well as others. I just think that's an important distinction to make :)
