Symmetra being autistic is honestly very important to me???
Like, we rarely get an autistic character in media outside of the rather offensive (in my opinion, at least; we all have different thoughts on this and I don’t speak for every autistic person) stereotypical portrayals, like Big Bang Theory’s Sheldon (ugh).
Not to mention she’s a female autistic character; those are even rarer because people frequently see autism as a thing exclusive to cis men.
And anger over turret cheese notwithstanding, she’s generally well-liked by the fandom.
AND her autism isn’t the only thing that defines her.
I could put this in a lot more words but I’m too tired right now.
