As somebody who has an autistic relative, I can’t help get angry when people “headcanon” autism on characters like it’s some kind of cute personality quirk and not a serious learning/social disability.
I love my brother to death and I would never change him for my own sake, but his life would be so much easier if he wasn’t autistic.
Please don’t treat the condition like some kind of trope, or use it as some kind of “special snowflake” token for fanfics.
If you’re going to write about it at least do your research. Not every autistic person has major sensory issues with sounds/textures/foods.
