I too think it's to broad a term. When my son was diagnosed with it 13 years ago most people I met with autism were like him. Non verbal, tantrums, stimming etc. My son is now 15 and through constant training the last couple years has only started using the toilet, feeding himself and almost stopped the tantrums. Though in the last 5 years or so I've met so many autistic people that you could hardly tell. I think it's a quick diagnoses.
