Asperger's syndrome and attention deficit disorder are not mental illnesses. These people are not crazy, just different. While depression and anxiety are mental illnesses, they do not make people violent. By implicitly treating all four diagnoses as mental illnesses and by linking all four to murder, you have contributed to the misunderstanding and stigma that make the lives of both the mentally ill and the neurologically divergent harder — and more dangerous. People diagnosed with autism are often the victims of violence, not the perpetrators.
