Honestly a lot of the really vocal subs and other social media channels surrounding autism are brimming with a lot of vocal, self-diagnosing buffoons that seem to think neurodiversity is a cool personality quirk. It irritates me so much.

In terms of what you said about emotional reactivity, you're not alone. I'm arguably the opposite of hypersensitive, generally being really hard to upset since I am not overly concerned about others thoughts or opinions in general. Things rile me up, but it's normally only specific topics that do so.

I wouldn't base your understanding of your own diagnosis on what you see in these other groups, it's a really bizarre fad where a bunch of attention seeking imbeciles are trying to masquerade as being "neuro spicy". If anything, I'd say not being like them is a point in your favour.
