Hi Mia

I do think talking about autism has more likely more chance here than Steam, itchio has its bad side as you noticed but also good side with enough freedom for important things and more or less freedom  even if their recent changes about nsfw is probably a bad move for the wesbite itself and takes freedom from people.

When 'normal' people sees Autism they will instantly think like "oh this person is fool" and such because they do not understand and are following the leading tendencies to follow the stupid standards of the world. 

Each person is different whether they are 'normal' or 'autistic'

Hopefully more people can come across your visual novels and see your message differently than the standards view of the world.
