It's a disorder. I have it. It's affected my life in mostly negative ways, despite the few positive things it brings.
It also makes me do things or think differently, but it is a disorder which causes the differences from NTs. It's interesting, just calling NTs NTs is politically correct to avoid offending those who would otherwise call them "normal."
I don't mind it, but I still refer to NTs as "them" or "everyone else." Haha.
