Autistic people are not a race. They are people with a disorder. By your logic, everyone whose depressed or schizophrenic are part of their own race. You are actually doing nothing to help the situation, making those with mental and development disorders feel even more isolated by claiming they belong to a different race.
I can barely stand to look at these two. they'd do well to actually listen to the people they are trying to "cure", perhaps they'd learn that people with autism have contributed to this world more than they will ever know or even dream of doing themselves.
