Autistic people are given bad representation in the media, normally being portrayed as stupid or unable. In other cases, people don't even show autistic traits but are called autistic for what the media calls "representation". That is not true representation.

Peter Parker/Spider-Man in the MCU shows several traits of Autism, namely his jitters, lack of patience and inability to read social situations. This isn't a big ask and would help show autistic people in a positive light. It doesn't have to be big, maybe just a subtle reference

Many people consider me and my autistic friends stupid and retarded, but if a mainstream superhero had autism, maybe people would be able to see we're not that different. For the autistic community, please. Please help us shake the negative stigma surrounding our condition
