No, it does not generally mean that. For sure, it MUCH more commonly means the opposite.
My stance is backed by me actually knowing what I am talking about, and understanding language, and having both studied and being qualified in that area, and knowing the way language evolves and changes and most importantly the way it absolutey does not work, which is the way you are saying it is. Furthermore it is based upon having read about the origins of the term as we can trace it back. Frankly I don't give a tiny toss about your dismissal of my opinion- you are simply speaking in ignorance. The amusing thing is how you really like to look down on people using such a phrase; watching such unbridled ignorant arrogance- smug too- always raises a smile.
Why you cannot accept these things happen in language is beyond me. What about "Tell me about it?" Can be meant literally, Very, very often means the opposite- "You don't need to tell me about it." You cannot possibly complain about the caring phrase but accept that and maintain any amount of intellecutal credibility. And you will find you use such phrases all the time.
