Everyone's a little bit autistic.
When I was undergoing training to supervise Autistic children and adults we covered the spectrum. Quite amusingly every single person on the course felt a little freaked at first to see that we all demonstrated some attributes of Autism. Thing is .. it's about the quantity and severity of those attributes.
There is a major difference between a meltdown of an Autistic child who has been unable to accept a change in plan versus a spoilt or unruly child who does not have a toy they want. A child who is truly autistic will have parents who are concerned about the childs future. Will they mix as an adult? What will happen when the parents die? A child will get away with behaviors that are not widely accepted in adults.
You need to draw the line somewhere and for me, it's where the person is diagnosed because they need lifelong assistance. Not because they show a mild attribute of the autism spectrum and go on to live a healthy and independent life.
So to paraphrase myself "The survey is a crock"
