I mean I'm wondering if it's comparable to like say deaf culture. People who are born deaf are part of a distinct culture that doesn't see itself as handicapped and views it as a different way of viewing and experiencing life.
Autism is real, but I do believe that many people are misdiagnosed with it, like people who just have bad social skills are diagnosed with autism. I do believe that theres alot of people who are misdiagnosed with it.
It most likely exists. I've met people who were autistic. I actually suspected it most cases before being told they had autism. Of course, some aren't obvious and there are people who like to use autism to their advantage.
