Honestly it's difficult to expect people to communicate all the things in the bucket that might apply to them. Naming the bucket is easier for a lot of purposes.

I get that. On the other hand, by making the buckets smaller, you're forced to specify the corresponding phenomena a lot more. Which might actually help people understand what applies and what doesn't, better. Understanding something is pretty much a prerequisite to communicating it.

EDIT: I misread your comment earlier, ignore the above paragraph. I definitely get how exhausting it might be to list off everything. I suppose I feel the Autism label is too big at the moment to communicate effectively though. See the following, I think it still applies.

It also helps people on the other end. If someone says they have "Misophonia, Aural sensitivity, and Rejection Sensitivity" I would understand a lot more about their situation than if they simply said they're mildly Autistic.
