From the Autism Society of America:
One of the most devastating myths about children with autism is that they cannot show affection. While sensory stimulation is processed differently in some children, they can and do give affection. However, it may require patience on the parents’ part to accept and give love in the child’s terms.
Thank you, Autism Society! I spent two years having concerns about Emily, while people gave, “but, she’s affectionate” as a reason why she “couldn’t” have Autism. *sigh*
