No, either you have autism or you don't. It's like being pregnant, you can't be a little pregnant
I should have said: not many of who we know
I'm not sure about that, can you elaborate?
As someone who got their autism diagnosis in the past 18 months there are certain ways that someone with autism may have strengths in particular fields of interest. Our interests tend to be hyper focused and almost all consuming. So someone with autism may obsessively think about a certain interest or thing and learn a lot about it, with the negative being having little to no interest in most other things that the general person will be expected to know/learn about. In other words we tend to be specialists at certain things that we're interested in, but we'd likely have some weak areas in some things you might expect someone to know about life, general stuff, pop culture maybe, things like that.
So lets say you are someone with autism and your particular field of interest is playing football. You will likely be someone with more time studying football and thinking about it, so you might have down particular techniques, been able to copy some popular players via analysis, might be better at understanding tactics (some people with autism are especially good at recognising patterns) and so on.
But then there are the downsides which someone with autism may or may not have - communication, fatigue from working harder to fit into social situations, they may have trouble doing delicate things, balance, over or undersensitive senses - being uncomfortable with what the average person might consider a reasonable amount of background noise, light, smell, taste
And so someone with autism will likely have many strengths and weaknesses in related to playing football. They might be amazing with the ball and find space on the pitch, or make runs splitting the defence and waiting for a pass with ease identifying a tactical edge. But they might also find it harder to get along with teammates, or be on the same page and understand what those players are thinking. They might find playing at a consistent level hard due to constantly changing circumstances. They might struggle with last minute changes being asked to play when they were going to be a sub. They might find it hard interacting with fans and signing lots of photos and doing media. Many things that a footballer would just be expected to get on with. A lot of those things create more stress for someone with autism and they would likely need more down time/peace and quiet than others.
