Low IQ in non-verbal autistic people

"Especially damning are the assumptions that my intelligence is low because of my thwarted attempts to respond the way others expect; with verbal words. I can remember a time when a person said to Mom that I have a very low IQ of 40, and I wanted to scream, NO! But I couldn’t. It was horrible not to be able to defend myself."
