To be diagnosed with ASD, a person has to have seen medical professionals and often had several assessments, for children it's often multi-disciplinary assessments and a diagnosis can take years to be given.
Parents often have their integrity honesty and parenting ability questioned, read through this thread for a small sample of what some parents have to do to obtain a medical diagnosis for their children, some of us have literally had to fight for years.
The term 'label' demeans the fact that child has not only a recognised medical condition but a recognised disability. Only people with a combination of traits 'which limit and impair everyday functioning' will be diagnosed with ASD.
Using the term 'label' for a diagnosed medical condition - why would anyone want to do that?
What do you do when asked to provide evidence of your child's ASD as proof that he needs support, do you hand over his medical diagnostic reports, or do you give them the label off your jamjar?
Was he diagnosed by medical professionals, or someone who makes sticky labels?
Why would you even want to demean, diminish, minimise your own child's medically assessed condition?
Labels can be removed at any time, a medical diagnosis of autism is given only when - to quote the NAS diagnostic criteria
www.autism.org.uk/about/diagnosis/children.aspx
'a person will usually be assessed as having had persistent difficulties with social communication and social interaction and restricted and repetitive patterns of behaviours, activities or interests since early childhood, to the extent that these "limit and impair everyday functioning".
Also, autism is a lifelong condition, not something you can grow out of, it's not a disease, there's nothing to "cure"
The above also answers the question of why we are emphatically NOT all on the autistic spectrum.
Anyone can have traits, but they will not be medically diagnosed as autistic unless they fulfil the diagnostic criteria.
Again, it's demeaning and frankly offensive to claim to be disabled when you're not - which 'we are all on the spectrum' does.
Good explanation of the spectrum here theaspergian.com/2019/05/04/its-a-spectrum-doesnt-mean-what-you-think/
