Actually, HFA is the term that "got me in the door."
Came from a family/friends that believed that you're only an alcoholic if you are always at rock bottom--constantly drunk, no job, no spouse, lost kids, legal problems, etc. Even though I knew my drinking wasn't working in my life, I didn't fit the above criteria, so what did I do? Kept drinking.
Once I heard the term HFA, I thought, "THAT'S ME!" No escaping the fact that I had a problem. I might have thought that I was keeping it all together, but I so wasn't.
The key word in high functioning alcoholic is alcoholic. To me, it doesn't justify anything, just acknowledges the facade and warns that it will inevitably come crumbling down.
