You know what's kinda crazy? It isn't even that hard to do.

Your typical autistic person you'll run into often enough to have a real conversation with, all you gotta do is explain one of those typically unspoken rules, maybe answer a few questions, and it isn't a big deal. More other than not, not only will they gladly try to do things a different way, but they're more likely to do so in a friendly and chill way than neurotypical people learning a new explicit rule at work or whatever.

Yeah, there's exceptions, but my experience with autistic people has been very positive once I figured out to just be honest and direct. Not that it was an overnight realization that dropping a lot of the unspoken rules could improve communication.

Again, on an individual level, you deal with the individual, there isn't a monolith there.

I think this is more true for autistic people

I've definitely had this experience before. Why are people such jerks, if someone asks the rules because they aren't sure or it isn't clear just tell them the rules. It makes it feel so unwelcoming when people refuse to tell you the rules and expect you to read minds.
