I think Oliver's point about other's being educated about Autism and learning some of the general do's and don'ts of interacting with people with Autism is a good one, same goes for people with OCD, or any mental illness. When you're dealing with someone with chronic depression, why yell at them for saying something negative, it's just what they're going to do. If someone with ADHD doesn't listen to what you're saying, do you yell at them? Of course there are boundaries to be set in every relationship from acquaintance to friend, to lover, but I think not blaming people for something they're naturally prone to doing is a good start, especially if they're putting in the effort to manage their symptoms.
