U.S. Health Secretary Robert F. Kennedy Jr.'s stark comments about children with autism have splintered a community of millions of people who are living with the disorder. The health secretary asserts children with autism will never pay taxes, hold a job or go out on a date. For some families, Kennedy's remarks are an overdue recognition of the day-to-day difficulties for families with autistic loved ones. To others, Kennedy deeply misrepresents the realities of their disability, provoking concern about his ability to handle a sweeping assessment of the disorder. Kennedy plans to launch a broad-based study of what causes autism, a complex developmental disorder.
