I thought this was the case, it drives me nuts! I used to always say SAD or SP but now say SA meaning the disorder. When I say it out loud though I think Social anxiety, a common thing among people (like stage fright, or nervousness). But when I see the thread "would you date someone with SA?" I think Social Anxiety Disorder, because just social anxiety alone is a quality many people have in situations, and gives the question a whole different meaning to me. Ah it's just the semantics drives me nuts, sometimes I think one thing is being said but I'm totally on the wrong page about.
