This is an adequate "first-dive" and introduction to the Xenos concept and how one can look in a positive way upon what most of society finds disabling and in need of elimination. You should feel good about your manner of living and contribute as your abilities allow.
There are several assumptions that are made in this document:
Society's expectations of what a person should be can be compared with a cookie cutter (the black line). People are expected to fill that cookie cutter completely, which is what a lot of people call being "well-rounded". The ideal goal in our society is to be well rounded, which is to have some ability or interest in all acceptable and anticipated areas and no serious deficits anywhere. Our society assumes that nearly everyone has (or should have) sufficient dough (or ability) to fill in the established cookie cutter expectations.
As a disabled person, you are deficient somewhere and that is a problem for everyone. Other people feel badly about the fact that your cookie cutter is not filled in everywhere and they want to "help". Society has decided to form entire industries for the purpose of trying to make disabled people more "perfect".
Fortunately for everyone, these Xenos people can often learn to steer their obsessive abilities toward interests that make the world a better place. It was Xenos-type people who created industrialization, telephones, the light bulb, radio, television, nuclear energy, computers, and ultimately iPods and iPhones, as examples. No one can doubt that people like Albert Einstein, Thomas Edison, and Bill Gates are pretty obsessive and odd and were able to do things that normal people cannot do or would have never thought of doing. Thankfully, many people were willing to ignore Einstein's unkempt hair and interesting mannerisms and focus instead on his theory of relativity!
Unfortunately for the Xenos, society doesn't like obsessiveness particularly. It gets in the way of making people well-rounded. Society's institutions (think about schools as an example) are designed to produce and service people whose ability and interests fit into the established societal cookie cutter. A Xenos person will have serious problems and cause serious problems when faced with a world (such as ours) that is heavily and inflexibly oriented toward institutional well-roundedness.
You can see in the picture above that there is some dough outside the black line. This is the indication of someone obsessively pursuing an interest or ability beyond what is considered normal and acceptable. To make up for things required to follow an obsession, material is missing from other facets of life. Often, the Xenos person is poor at mundane everyday tasks like hygiene and may lack common sense or common manners. In a typical Xenos, the basic dough (or level of interest or ability) is roughly the same as (or greater than that) in a "perfect" person; it is just distributed differently, some of it outside of the cookie cutter definition of what is normal and acceptable.
Our society grows more and more myopic and can only see value in what is considers to be normal and (frankly) profitable. If you were to cover over the dough that is outside the black circle in the picture, the Xenos person looks just like the disabled person - someone who doesn't have their cookie cutter filled in. To most people, a Xenos person is considered disabled, being practically unable to see ability outside of the boundaries of social normalcy.
Most disability professionals would excitedly attack that unsightly blob of "wasted" ability outside the established circle in the picture above and chew up someone's childhood or entire life trying to fill in that missing place in the cookie cutter that dictates how well one holds their fork. Thank goodness there were no therapists engaged in fixing Einstein - who knows how much we would have lost!
It is important to note that there can be truly disabled people among the Xenos, just as there are among typical people. I am sure you can see the picture in your mind of the cookie-cutter and a small amount of cookie dough stretched out toward some obsession, resulting in very little lying inside the circle. There is some small need for therapists and doctors and psychologists for those people, with an understanding that you cannot get the obsession out of the Xenos and focus can be set on handling communication problems and other things that can help the Xenos achieve their potential to go where no normal person could ever go!
