I don't know where the puzzle piece concept came from (was is Autism Speaks? I'm not linking to them but feel free to have a look around this.) but I will bet my last penny that it wasn't run by anyone who is #actuallyautistic. Sure, people with autism can be difficult to understand but then, people without autism can also be difficult to understand. Yes, life with autism is complicated sometimes as life without... oh, you get the idea. Of all the aspects of existence to choose from, why select a demoralising one that doesn't actually speak solely of us, the autists? In simple terms, not only is this not a kind or helpful way to describe a human being, neither is it a correct description of autism. I suspect it was chosen, and is still widely used, by so many non-autists who neither consider nor comprehend its connotations. Indeed, it's become so ubiquitous, many with an autism diagnosis now unquestionably associate themselves with it.
As an option, I wonder how many with autism can see themselves using a clean, geometric symbol instead?
Let's talk colour and demographics later :)
