Like, in your youth - in the teens or even early-mid 20s (rec leagues), did people ask if you did sports and if your answer was "no", did they ask WHY?
I don't know what is it with NT culture, such as it is - but it does seem like young men are virtually conscripted into sport. Like it's to uphold some sort of gender expectation. Here in Canada, that expectation is pretty strong but not as much as our neighbours to the south, especially in the Deep South where they might call you "gay" if you don't play sports
I can still remember in my teens, when my special interests at various times were periodic table elements, the history of Hollywood and the Oscars, and geologic eras... at no time did sports ever enter the realm of special interests. In fact I recall one time on a break at a McJob, my co-workers would look at the papers in the break room and talk about sports articles and stats, and I'd just be buried in my puzzles, comics, or current affairs. They mocked for that saying "ha ha, Jayo's no jock, he's just into the dorky stuff".
For me, I tended to avoid organized sports AMAP, due to a certain PTSD-like sentiment that remained from any involvement in it. It just conjured up emotionally painful images of other kids intentionally throwing sporting projectiles at me, bumping into me, tripping me etc. and then claiming it was an "accident" while peers would laugh and the supervising adult rarely did anything about it
Now i I was good at sports, maybe that wouldn't have occurred as often - maybe they would have been more tolerant of other differences like lack of non-verbal fluency or odd speech patterns. But I digress.
So when people asked me "why" [don't I play sports], I just resorted to telling a half-truth, that I suffered a lasting injury playing sports (soccer) and I just stuck to "Eastern" sports like martial arts. Which was true, I was enrolled in martial arts, and I did suffer a soccer injury but not a long-term debilitating one. But nobody had the right to know the full truth, it was really none of their business - I just wanted to mitigate their judging me.
The analogy I used on at least one other occasion on WP, is that an Aspie wishing to join an organized sports team of NTs is like a Jew trying to infiltrate a skinhead chapter
