Relate-ability to others within the same category of diagnoses is not the issue when it comes to spectrum disorders. That doesn't come into play at all, and it shouldn't. There are various types of Autisms. There are various severities of each type of Autisms. That's why it's a SPECTRUM. Some people will relate to each other, and some won't.
Just like some people with Diabetes II will relate to other people with Diabetes II and others won't. Or some people with 12 children will relate to other families with 12 children and other families won't. Or some people with Bi-Polar I will relate to others with Bi-Polar I and others won't.
Anything that can bring Autism into the spotlight and get people to be ACCEPTING of people who have Autism and help shatter some of the negative stereotypes that aren't true is good publicity. This young woman is amazing. She's overcome so much regarding her disability, and she still has to take everything day by day and do what her disability allows her to do. She can do what it allows her to do.
Because it's not true that people with ASD can aspire to "anything." They can only aspire to what their particular Autism allows them to aspire to. Attempts to strive higher occur when there's a feeling of capability and push to overcome... but that's not always possible.
And of course there are some people so severe with their ASD that they'll never speak or toilet on their own. They'll never be able to use Assistive Technology of any kind. Most autistics are not like that.
EDIT: The goal of people with Autism, especially those in the public arena, IS NOT TO APPEAR NORMAL aka NEURO-TYPICAL. That's a fallacy and it's ignorant to assume that that's what people with ASD are striving for. People with ASD don't want to "be normal" or typical, they want acceptance. They want the general public to be educated about what Autism Spectrum Disorder actually is. The goal is not finding a cure or appearing normal. The goal is learning to function in a world that doesn't think the same way and isn't built for them... and to eradicate bigotry, ignorance, and intolerance of any level of disability.
