To me, my idea of neurodivergence is that it's a more neutral term what we'd typically call neurodevelopmental disorders, and could potentially be extended to personality disorders. Neurodivergent people are those with (typically) lifelong differences in brain function. I think it's a helpful concept at times but I also think it's far too vague and more specific diagnoses exist for a reason.
I'm torn on including personality disorders because on one hand, they feel more squarely problematic (particularly as someone whose mother is Borderline), but on the other, it's possible that "feeling squarely problematic" is influenced a whole lot by culture and personal opinion. I've experienced being judged by other people's shitty personal opinions too often to feel comfortable doing it with other people.
