I dislike the puzzle piece because it implies we're incomplete or a puzzle for NTs to solve, but I also dislike the infinity because it implies we can do aaaaannnnyyyything and aren't held back like with any other disabilty, as if Mozart/Beethoven level prodigy is the norm.
Also, I really don't get the puzzle piece vs. infinity debate; I understand that Autism Speaks is garbage (and even that's an understatement), but the whole argument really befuddles me.
