1.A disorder where "suffers" have nothing at all in common with each other - all "syptoms" are normal personality traits that everyone has at least one of.more...
2. Like a lot of "Mental Illnesses", this one has been discovered/invented in the last 10 years or so.
Don't get me wrong, a real mental illnes is a horrible thing to have. By a real one, I mean something like Paranoid Schizophrenia, Bipolar Disorder, or Major Depressive Disorder. However, more "Mental Illnesses" have been discovered/invented in the last 15 years than in the last 1000.
This is because of society's growing complacency towards high-energy snack products, caffeine-containing drinks, and idiotic television propaganda telling you what you should eat and drink and buy and do. As a result of this complacency, many people in society (especially children, as they are more susceptible to this sort of treatment) are now acting a lot differently to how people acted several decades ago.
As a result of this change in personality, more and more "Mental Illnesses" are being discovered/invented every year. Neurotypicality is just another case of corporate-paid doctors inventing a syndrome. Why? So that parents can have an excuse as to why their kids behave so bad, instead of just admitting that their children have been subjected to too much of society's propaganda.
Neurotypicality: you don't have it, you're just badly-behaved.
