As someone with an autistic younger brother, I'd like to consider myself as having a little bit of perspective on this matter. On one hand, if I were to be a completely selfish sociopath, having an autistic brother would be the greatest thing ever. He barely talks, he never complains, he plays hand-me-down five year old videogames (by choice, mind), and aside from whenever he's truly distraught or we actually feel like having a conversation with each other, he never really bothers me for anything.
However, well-rounded people have empathy, and I've empathy especially for my little brother. Like most autistic people, he has some degree of mental retardation, and his language skills range from short, dozen-word sentences too giggling profusely. I try not to think about it; for if I did, all I'd feel is pain, and pity, and sorrow. The story gets worse the further you go down the rabbit hole. I know classmates of his (14 years old) that were just toilet trained last year. I know a single mother, a social recluse due to her psychopathic over-protectiveness of her two autistic children, that keeps tabs on every car in town in fear of her abusive husband coming back to beat her. My brother's teachers this year are even worse! So incompetent and wishy-washy are they, that one of my brother's former classmates physically resists going to school. He's also gained fifty pounds in three months, and uses a cane to walk.

Like if a few thousand years ago if we practiced eugenics through breeding we could of all been wiped out through the black plague. Another example would be sickle cell anemia in Africa being resilient to malaria.[/font][/size]
