I don’t agree with this take. I have social anxiety and difficulty empathizing with people in certain respects. One of my children who is diagnosed has these two issues and some sensory and dexterity issues, issues with adapting to changing circumstances, and a very limited ability to regulate their responses to frustrating situations to the point where they’ll go on rants with crying and anger that is white hot (a “meltdown”). This child is what is commonly called “high functioning,” though: anybody who has not observed them long enough could easily only ever see one of these behaviors/traits, and the child is in a regular classroom and has been identified as quite gifted in some subjects.

I’m not on the spectrum, and would never claim “I’m a little autistic.” I might have before I had the kid, but definitely not now. My kid’s autism symptoms are really minor compared to many, but it’s so far beyond the kinds of quirks you’re referring to as to be obviously and starkly different.
