Thank you.
They would say to me that if I was smart enough to become a paramedic, then I was smart enough to know how to not be autistic.
Autistic people sometimes have an all-consuming, obsessive interest. Sometimes it's trains, dinosaurs, light bulbs, etc... It's a symptom of what used to be called Asperger's Syndrome.
My mother would tell me that if I made "being normal" my special interest, then I would be normal. Since I don't choose to make normalcy my special interest, then I choose to be autistic.
If they accomodate my autistic tendencies, then it's like enabling an alcoholic or a drug addict.
Sorry, but your parents are wrong in their assertions. Not even a smidgen of truth in them.
