Well if a child's autism is so mildly presenting that it doesn't interfere with their lives and development in a major way, then why does it need to be "caught"? Wouldn't diagnosing someone whose autism doesn't negatively affect them possibly create more problems for them? As in, it could lead to people giving them therapy when they don't need it, lead to lowered expectations by parents etc?

Something only needs "treatment" when it actually is negatively affecting them, right?
