I personally don't believe in autism. I'm not saying that these people are all fully cognitive. Some clearly have a complete lack of emotion, some lack the ability to speak, etc etc
My problem is a large variety of conditions, disabilities, and actual abnormalities are given this meaningless blanket umbrella term. That shyt is like "schizophrenia". No one symptom or set of symptoms exist to rigidly define what it is and isn't.
Nobody can show me a diagram of this supposed "spectrum" that isn't so broad that it could include everyone.
A lot of people are just weird, undisciplined, and instead of being given specialized treatment and training to overcome their shortcomings and differences are given a label and pass to not even attempt to improve themselves.
