I keep seeing people on this site say the most absurd nonsense about neurotypical people. Think of a human state of being. That state of being is experienced by neurotypical people. Nothing human is strange to me, as the line goes.
You're seeing that stuff from people who have been treated quite badly for not being neurotypical, so maybe have some compassion and a sense of humor about it.
And also maybe consider that the neurodivergent people have noticed some patterns /because our brains work differently/.
In this case I think the better term for the op’s point would be “neurotic” John Roberts doesn’t come across as a very neurotic person. Or he’s good at masking it in public. Or his neuroses are focused on some more discreet thing. Like maybe he’s a hypochondriac & worries constantly about cancer?
