As someone whose whole entire job has been working with autistic people for the past two years, Sia is a complete twit.
What an absolute idiot. Even people who know nothing about the autistic community know that Autism Speaks is a group full of weirdos who are essentially for conversion therapy and against embracing the beauty. And casting a neutotypical person in the main role, especially when films like Peanut Butter Falcon are making a push towards the normalization of NOT doing that... how tonedeaf.
And now she's out here throwing a tantrum on Twitter and insulting the people she's supposed to be uplifting. In under 24 hours, she's been exposed as an absolutely trash human being.
Edit: Finally watched the movie and, surprise, it's garbage aside from my personal feelings on the production! Truly couldn't have seen that coming!
