Pay attention to people and try to be empathetic. Do this to everyone, not just those you suspect of being autistic. That's all anyone can ask of you, and it works. Autistic people aren't aliens - if you engage empathetically they will respond positively, like any other person.

This is the answer. I’m autistic and I don’t want anything for myself that I don’t also want for everyone else. All I want is to be treated like the individual human being that I am. I have specific things I’m good at and other things that are difficult or impossible for me. Other people have different abilities and challenges. Stop acting like there’s some “normal” that we all need to aspire to. No individual is normal.
