Why a separate category for milder forms of it?
Just because someone may have some overlapping symptoms or behaviors doesn't mean its the same thing but less.
You have a highly social person who diagnose as autism because they get fixated on things, big woopie. That's completely different from those who are broken socially IMHO the base core of autism is they lack the ability to communicate mostly non verbal cues. Yet those social butterflies who excel at it, and always have as a normal person, get classified as autistic to the point where those who have real autism (high or low) get drowned out.
So sick of hearing people claim autism over fixation on a topic or some such. Yet they perform like an actor all without spending years of training/counseling to pretend to be human let alone make eye contact.
I'm also so sick of all the parents with puzzle bumper stickers, they don't accept autism. their kid is their autistic little "pet" that they show the world how good of parents they are. I've seen countless people who "love" their autistic kid(in most cases the kid really is), but just give him a screen to be alone in the corner, yet most of those could be nurtured into a one who wouldn't be reliant on them or even make more money by them
Sorry, guess I let the rant take over
