I get that technically Autism is a "spectrum" of disorders, but what's a common thing that can be found in every person with autism?
As I understand it, to have ASD, you need to be...
1. Absolute dogshit when it comes to social skills
2. Obsessed with a very small amount of interests, repetitive motions
3. Extremely sensitive to sensory experiences (ie. bright lights, loud sounds, gross smells, etc.)
The first one is extremely vague, and can apply to at least a third of the general population, and half this website. The first part of the second one (limited interests) can be found in any boring, untraveled person out there (myself included). However, I can grant that restrictive, self-rewarding motions (such as repeated handclapping, vocalized beeping noises) aren't normal in adults. The third requirement also isn't common in the average population.
How can all these people be diagnosed under a single spectrum, when the symptoms are so varied, vague, and unconnected? People with autism themselves vary in intelligence from the above average/brilliant (Asperger's), to the below average/borderline retarded (average Autism). We still don't even know what causes the disorder; other than familial genetics, combined with the ages and social habits of the parents during conception/fetal development.
The two autistic guys that I care for are both extremely stupid and are borderline perverts; but the first is sensitive to loud noises, has extreme anxiety, and can't drive or live by himself. Whereas the second is calm, can drive/live by himself, isn't very sensitive to sensory experiences, and is a bit of a dick to the first.
Side note: Only if you spend more time taking care of people with autism than I do, can you complain about me talking deuce about autism.
