That’s not how that works. ASD is one thing; behavior is another. However.
My son is on the spectrum, not diagnosed until his mid teens. He’s attended some college so far, and took advantage of a support program at the school for people with an ASD diagnosis. The first year, he was in a dorm specifically built for this program, so over the course of the year, he got a lot of new exposure to “people like him.”
Just today he was remarking (again) about how “sheltered” and “coddled” a lot of the other students in this program are. He sees how people respond to situations, and he sees how parents interact with their kids when visiting, moving in/out.
My son is glad to not have had a diagnosis until later on. He recognizes that having gotten some bullying in school - while definitely not desirable, did happen - forced him to be introspective, and forced him to figure out coping mechanisms on his own.
Those are beneficial skills that are well taught by experience, and overprotective parenting (whether the kid is on the spectrum or not) reduces the ability for kids to learn those skills.
Again, that’s not how that works. ASD diagnosis is a lengthy process involving multiple days of interviewing. When someone goes undiagnosed until adulthood, but has figured out their own coping mechanisms and strategies, that doesn’t mean they aren’t on the spectrum anymore. As above, ASD and behavior are two different things.
Have you been diagnosed? If you had, I’d have to think you would already know the above.
