If you, a family member or a friend have a disability that has gotten in the way of social situation going smoothly, often an explanation is in order.
Once upon a time it was considered rude to refer to someone’s disability in social situations. Delicate way to talk about disabilities was saying ” a person with ” or “a person of”.
But about 25 years ago or so, a cascading series of campaigns from different disability groups made it very clear that a disability is not something to be ashamed of and hidden and it becomes Who You Are so don’t be afraid to talk about it.
Since then they’ve been trying to educate the public varying degrees of success and failure.
Of course you call somebody by their name. Of course you don’t refer to a disability unless there’s a need to.
But when the need arises do you talk about it awkwardly or straightforwardly?
It’s not one-size-fits-all. It’s an issue that apparently the general population is surprisingly unfamiliar with.
So there’s my explanation best I could do.
