"No more puzzle pieces, okay?"
God I hate autism awareness month. :I
If you want to support autistic people, the Autistic Self Advocacy Network and Autistic Women's Network are the way to go. For starters, they're actually run by autistic people, which makes a world's of difference. Autism Speaks does not want to help us, but to eliminate us (or just make money off of the autism stigma, which ever).
Here's a link with a lot of info, including links to more charities, though I'll link to the ones I mentioned separately.
