I had to be taught that but outside of that, most people who didn't spend too much time with me then think I am smarter than average and are willing to rely on me for help with some stuff. I am proud because Asperger's is related to how one's brain is wired if I was embarrassed or considered Asperger's to be defective it would take a toll on my mental health because then I would be thinking of myself of a defective thing and defective things are usually thought of as something that should be thrown out.
And sometimes the inability to see that the objective world that exists is not the same objective world that we see. Due to how the brain interprets sensory information from the objective world.
An example taken from your own text:
The reason that you are not supposed to tell a fat person that they are fat is cause by saying you are fat you are essentially pointing to that persons irrational behavior(eating to much).
The fat person does not want to think about their own overweight, it will lead to them start thinking about their own irrationality. Something that will then cause them to feel that they are a failed person, causing negative emotions.
Reality can be analyzed in many dimensions.
Anyway, it appears to be only a matter of time until there is a "provable" test for autism. See, for example: https://molecularautism.biomedcentral.com/articles/10.1186/s...
There are also observable (via fMRI) differences in the brains of people on the spectrum: http://time.com/3614487/fmri-autism-diagnosis/
Autism is the ADD/ADHD of the 'oughts. Overly diagnosed (come on, 1:55, really?), misunderstood (is the creepy guy who stares too much and never says anything a freak or is he autistic?), and often times used like a crutch by those who both want an easy out and/or don't want to take responsibility for their actions (oh, I have mild Aspberger syndrome and your offending me).
The notion of a "spectrum" is ludicrous too, how ever can we lump in someone who's a bit slow yet fully independent with someone like the above poster who's 8/10 year olds can't go potty on their own? This is a disservice to people on both ends of that "spectrum."
