Well, I don't really know … but I don't think we are throwing inbreeding/incest/mental retardation in with the autism spectrum, are we? At least in my mind, that's not what autism is. I am looking at the prevalence of babies, who are "normal" at birth, and developing all the milestones, to suddenly drop into this condition, where they lose contact with the world outside of themselves, and don't communicate, no eye contact, no hugs, emotions etc. It's not the same thing, look up the definitions.
