Yes. I was talking to a person at an event somewhere who attacked autistic people with obvious disgust. They said that autistic people were increasing due to chemicals and that we are a problem, and talked about them in the way an arachnophobe talks about spiders. I can't remember much more.
I followed by telling them I had been diagnosed with Asperger's syndrome several years before our encounter. They gave me a death stare but said nothing more.
