I feel like Furry is a big experiment in Culture just for Autistic people.
And I mean that in a Great, fantastic way. All the rest of our mainstream culture has always been by, and For, allistic people.
Now, we have culture that transmits and receives on the autistic perception spectrum. We have a culture of celebrated masks, of alter-selves, of Desired Presentations. And because we're all 'in' on the joke, disbelief isn't just Easy to suspend, it's Natural to do so.
