Can't it be that a neurotypical person is bothered by some autistic triggers? Would that make them neurodivergent? How many of those triggers do you need to have to be under that umbrella? 1? 5? 20?
It is indeed called a spectrum, and I think it gets so fuzzy at the edges that the only way to define where it starts or ends is purely arbitrarly chosen.
It's a bimodal distribution. There are people with few of these traits lightly, and people with many or with a few severe ones. Not so many in between. This already makes it an interesting line to draw.
