ASD doesn't make you an untermensch, even if it makes you feel like one. It just makes you different from the majority. There is nothing wrong with being different from the majority, though it can be inconvenient.
I dislike the "D" in the abbreviation ASD. Anything as common as autism can not be a "disorder" as far as biology is concerned. It is simply a variant, and it must have survival value in some circumstances, or else natural selection would have eliminated it. (I am referring to autism that arises naturally, not autism that is the result of actual brain damage during or after birth.)
Any trait that occurs naturally (i.e. is not the result of an accident) at a frequency greater than the mutation rate can not be a disorder. Roughly speaking, that means that any trait that you see in more than about 1 person in 30,000 must have survival value in some circumstances, so "disorder" is the wrong word. It may have undesirable consequences in other circumstances - the classic example is the sickling gene - but it is not wholly bad. Traits like homosexuality, left-handedness, gender variance, blue eyes, etc. also can not be regarded as disorders, for the same reason; they are much too common.
I hate to see any minority getting squashed by the majority, whether it is done deliberately or simply as a result of thoughtlesness and lack of understanding. It seems to me that the best response is not to hate yourself, but to fight back if you can. (I know that not everyone has the strength, or even the motivation to fight back.)
