Aspergers Syndrome (Although doctors have perplexingly renamed it to Autism Spectrum Disorder; I'd honestly rather have a Syndrome than a Disorder, thanks! Disorder implies it's purely negative.)
Let me introduce you to my friend Thomas Szasz.
I will disagree with you, purely on the basis multiple members of my family have continuing existence in part due to psychiatry and/or psychology (I'm making the assumption the quote refers to both) including myself, to some extent.
I'll disagree with you as a Psychology student who sees the DSM IV and its shift to DSM V.
But I'll poke them roots here. "Implies" is a powerful idea, just as much as many attributive words that connect something to a cause, like 'seems like' or 'feels like', it's a cognitive process helpful for our ways of understanding things; it should not be used as our only method to form conclusions however, because it's not a specific process. It's a process that gives 'possibly it can mean {x}'. It's not a process that gives "This means {x} so yeah. :I"
It does not mean an abnormality, since I'm using Psychological terms. Disorder means something that impacts multiple areas or aspects about your life, and may create distress from the symptoms experienced. It is not meant to have a negative connotation in of itself.
Also PDFs are your friend. I am being silly but I hope you can get it! :3Do explicitly note, the constant use of 'may/tend'. This is used because of having to acknowledge the general situation, while also giving acknowledgement to possibility in specific situations and the differences that may occur--"this may happen" {is a general statement underlying the idea because of certain reasons; it does not mean "If you have {x} diagnosis, this may happen to you because you have it o_o"...pretty much because post-diagnosis, there's always counseling and information-giving}. The use of 'may' or any other idea that gives the meaning of possibility is also to give mention to an applied context within the current reality (that means 'things that happen to someone in realistic situations, due to how many factors exist'), along with giving mention to statistical understanding, then backed up by qualitative reinforcement.
